@​composio/core@​0.27.0

Minor Changes

• c2bbfa8: Add session hooks. A hook can block a tool call before it runs, or block its result before the agent sees it.

  create() and update() accept hooks. On update(), hooks replaces the whole list and null removes every hook. hooks cannot be combined with experimental.sessionConfigId.

  const session = await composio.create('user_123', {
    hooks: [
      {
        type: 'before_execute',
        id: 'no_external_email',
        name: 'No external email',
        appliesTo: { toolkits: ['gmail'] },
        handler: {
          type: 'condition_check',
          condition: 'Sending email to anyone outside example.org',
          action: 'block',
        },
      },
    ],
  });

  A blocked call comes back from session.execute() and session.executeMeta() with resultType: 'blocked', empty data, the hook's message in error, and blockReason. Provider integrations hand it to the agent as a failed call with that message. Every result also carries hookResults when a hook applied.

  session.proxyExecute() and ctx.proxyExecute() now return resultType: 'completed' or resultType: 'blocked'. A blocked request has no HTTP response, so TypeScript code that reads status has to check resultType first.

Minor Changes

• e08c84f: Requires @composio/client 2.0.0-rc.18. The SDK now hands the API client its credential as the client's auth option and its organization and project as scope, instead of placing them in default headers. The apiKey, userApiKey, orgApiKey, orgId and projectId options, their environment fallbacks and the credentials sent on each request are unchanged, with one exception: with apiKey: null and only an organization API key (the orgApiKey option, COMPOSIO_ORG_API_KEY, or an x-org-api-key default header), every request now carries x-org-api-key, and so do trigger channel authorization and session.mcp.headers. Before, only the organization-owner operations did, and every other request went out without a credential.

  Credential and scope headers in defaultHeaders or createSession({ headers }) keep working, but the SDK folds them into its own options instead of forwarding them: an x-user-api-key or x-org-api-key entry becomes the credential every request carries, an x-api-key entry becomes the project key, and x-org-id / x-project-id entries become orgId / projectId. getConfig() reports the folded values (for example apiKey: null and userApiKey for an x-user-api-key entry) and no longer lists those entries under defaultHeaders. Setting more than one of x-api-key, x-user-api-key and x-org-api-key now throws a ComposioError; the API rejected every such request.

  On the client returned by getClient(), apiKey, userApiKey and orgApiKey are read-only and deprecated (read the keys from getConfig(), or authMode and scope from the client), and a per-call headers option can no longer name a credential or scope header. The API client no longer reads the environment itself: the SDK still honours COMPOSIO_ALLOW_INSECURE_HTTP=1, and no longer applies COMPOSIO_CUSTOM_HEADERS; pass defaultHeaders instead.

  The deprecated customConnectionData now requires val.access_token for S2S_OAUTH2, as the API does.

• 57de614: Requires @composio/client 2.0.0-rc.19. The SDK forwards the API client's log lines through a Console-shaped object instead of the client's removed Logger interface; what is logged, and at which SDK level, is unchanged. With rc.19, the client returned by getClient() no longer has apiKey, userApiKey, orgApiKey or logger, and its baseURL, maxRetries, timeout and logLevel are read-only: read the keys from getConfig(), and derive a client with withOptions() to change the others.

Patch Changes

• 9d26fb8: Fold OpenAPI nullable into the type in strict tool schemas

  toStrictJsonSchema no longer passes OpenAPI nullable through. Anthropic strict tool use rejects it on an object schema with a 400 for the whole request. A node with nullable: true now accepts null through its type (["object", "null"]) or a null branch, matching how the tool's arguments are validated, and the rewrite is reported as a nullable-converted change. nullable: false is removed as an unsupported-keyword-stripped change. omitNullToolArguments now keeps a null for a property marked nullable: true, as it already does for one whose type includes null.

• 3dd9a2c: Strip string format values that OpenAI structured outputs rejects from strict tool schemas

0.28.0

Minor Changes

• d2d4148: Requires @composio/client 2.0.0. POST and PATCH requests, including tool execution and trigger creation, are now sent once instead of being retried on a lost response or a retryable status, because a write can complete on the server after its response is lost. Other requests keep their retries. On the client returned by getClient(), a write retries only when that call sets maxRetries.

• e87ed85: Requires @composio/client 2.0.0-rc.20. The SDK imports the client's types from the one @composio/client/resources/* spelling rc.20 publishes and reaches nested types by indexed access; every type the SDK exports keeps its shape. With rc.20, the resources of the client returned by getClient() are plain objects typed by interfaces: the resource classes, Composio.Tools-style statics and namespace-member types such as SessionCreateParams.Experimental are gone, and the .js/.mjs subpath spellings no longer resolve.

• 3f3df9a: Requires @composio/client 2.0.0-rc.21. The SDK's behaviour is unchanged. With rc.21, the client returned by getClient() no longer has request(), Composio.Composio or Composio.DEFAULT_TIMEOUT: call the raw verb for the method (get, post, patch, put, delete), which takes the same query, body and request options.

• 54a935f: Requires @composio/client 2.0.0-rc.23. composio.sessionConfigs.list() no longer sends search, which the Composio API removed: the option is deprecated, ignored, and logs a warning when set; filter items by name instead. With rc.23, the client returned by getClient() no longer has cli.createCodactFailure (now under client._internal, typed through @composio/client/internal) or org.clanker.createClaim, and its sessionConfigs.list() no longer accepts search.

• 7434e02: Requires @composio/client 2.0.0-rc.22. composio.toolkits.get(slug) now returns meta.appUrl when the API sends the toolkit's app URL; it was always left out before. composio.sessionConfigs.get() keeps the require_approval lists of a stored policy, and no longer fails validation on a policy entry that only sets require_approval; SessionConfigPolicy gains the matching optional require_approval fields and the approval-only entry. Session hooks, blocked calls and hook results are read from the API types of @composio/client instead of SDK copies, with the same results and errors for well-formed responses; a malformed hook_results or blocked response is no longer re-validated by the SDK, matching every other API response.

• a5a1fc8: Requires @composio/client 2.0.1. Adds composio.experimental.customToolkits.create() and update(), which call the v3.1 custom toolkit create and update endpoints. create() takes userId ('all' to share the toolkit, or the user it is private to), generates the slug, and returns a connectLink for a private toolkit. upsert() is deprecated and logs a warning once per process; it keeps working.

  API-key auth schemes accept additionalFields.genericId with a required displayName and optional description to collect the value used by {{generic_id}} headers.

• d2d4148: composio.triggers.create() accepts type ('webhook' or 'poll', for a trigger that supports both) and pollingInterval (minutes between polls, which wins over triggerConfig.interval), and returns the instance's type, fallbackReason and pollingInterval along with triggerId. composio.triggers.listActive() items carry the same three fields, and getType() / listTypes() return each trigger type's type, types and requiresWebhookEndpointSetup.

Patch Changes

• e547eb0: Upload local files with the MIME type of their extension

  A file uploaded from a local path used to be sent as application/octet-stream whatever it was, so tools that check the file's type, such as Canva's design import, rejected it. The SDK now infers the type from the file name's extension (a .pptx uploads as application/vnd.openxmlformats-officedocument.presentationml.presentation) and keeps application/octet-stream only for missing or unknown extensions. The TypeScript and Python SDKs now use the same extension table, so a file uploads with the same type from either SDK and from the CLI. Files passed as File objects and URLs keep the type they carry.

• 30f8ca1: getExtensionFromMimeType now maps text/csv to csv from its table, matching the Python SDK. The returned extension is unchanged.

• f6368e0: Add the missing experimental option to the ToolRouterAuthorizeFn type. session.authorize() already accepted experimental: { accountType, aclConfigForShared } at runtime, but sessions returned by composio.create() and composio.use() rejected it at compile time.

0.27.0

Minor Changes

• c2bbfa8: Add session hooks. A hook can block a tool call before it runs, or block its result before the agent sees it.

  create() and update() accept hooks. On update(), hooks replaces the whole list and null removes every hook. hooks cannot be combined with experimental.sessionConfigId.

  const session = await composio.create('user_123', {
    hooks: [
      {
        type: 'before_execute',
        id: 'no_external_email',
        name: 'No external email',
        appliesTo: { toolkits: ['gmail'] },
        handler: {
          type: 'condition_check',
          condition: 'Sending email to anyone outside example.org',
          action: 'block',
        },
      },
    ],
  });

v2.10.0

2.10.0 (2026-10-29)

Summary

A small feature release: download() gains a decodeText option for saving a text part as the original file instead of as decoded text. Default behavior is unchanged.

Who should upgrade

No hurry unless you offer inline text/plain or text/html parts as downloadable files. Nothing changes for existing callers.

Highlights

• download(range, part, { decodeText: false }) returns the part with only the transfer encoding (base64, quoted-printable) removed. It skips the format=flowed unwrapping and the charset conversion, so the saved bytes match the original file. meta.charset still reports the part's charset. Requested in #455.

Features

• add decodeText option to download() for transfer-decoded file bytes (9c9bec2), closes #455

v10.3.1

10.3.1 (2026-10-29)

Bug Fixes

• apply the otp option in MailComposer too (1d4087f)

v10.3.0

10.3.0 (2026-10-29)

Summary

This release adds support for the OTP-Token header from the IETF draft draft-goto-otp-token, which lets mail clients and browsers offer a one-time passcode for autofill on the site it belongs to. It also fixes how a Content-ID header is encoded.

Who should upgrade

• Anyone sending one-time passcodes by email who wants them to be machine-readable.
• Anyone already setting an OTP-Token header through headers: before this release it went out MIME encoded and could not be parsed.
• Anyone embedding images with a cid that holds a non-ASCII character or a quote.

Highlights

• New otp message option: otp: { code: '123456', origin: 'https://example.com' } adds OTP-Token: "123456"; origin="https://example.com". The origin is reduced to its canonical form, only https (or http on a loopback host) is accepted, and invalid values fail the send with the new EOTP error code. See Message configuration.
• A custom OTP-Token header is no longer MIME word encoded. Line breaks and control characters are still removed.
• OTP-Token is included in the DKIM signature by default.
• A Content-ID header, from an attachment cid or set through headers, is now encoded as a message id rather than as text, so a cid with a non-ASCII character or a quote keeps matching the cid: URL in the HTML.
• Groundmail added to the well-known services.

Features
