Authentication

Send your token as a bearer token in the Authorization header of every request.

curl https://api.abconvert.io/v1/experiments \
  --header "Authorization: Bearer <token>"

The one exception is GET /exports/{id}/download, which takes no Authorization header: the signed link is the credential. Anyone holding a download link can read the data until the link expires, so treat it like the export it opens.

Tokens

A token belongs to one shop and reaches that shop only. If you manage several stores, hold one token per store. Create and revoke tokens in the ABConvert admin, under Settings → MCP & API Access.

Treat a token like a password. Store it in your secret manager, never in client-side code or a repository. If a token leaks, revoke it in the ABConvert admin. Revocation takes effect immediately.

Scopes

Scope	Grants
`read_experiments`	List and retrieve tests, read results, and create, poll, and download exports
`write_experiments`	Everything `read_experiments` grants, plus create, update, lifecycle actions, and schedule changes

GET requests need read_experiments, and so do POST /v1/experiments/{id}/results and POST /v1/experiments/{id}/exports, which read data and change nothing about the test. Every other request needs write_experiments. Scope and rate-limit budget are separate questions: see Rate limits. Write includes read, so a write token needs no separate read scope. New tokens default to read. Grant write only to integrations that manage tests.

Authentication errors

Status	`type`	`code`	Meaning
401	`authentication_error`	`missing_token`	The request has no `Authorization` header.
401	`authentication_error`	`invalid_token`	The token is malformed, doesn’t exist, has expired, or names a shop ABConvert can no longer act for.
401	`authentication_error`	`token_revoked`	Someone revoked the token in the ABConvert admin.
403	`permission_error`	`insufficient_scope`	The token’s scope doesn’t allow this operation.
403	`permission_error`	`api_access_disabled`	API access is turned off for this shop. Can occur on any request.

An expired token reads the same as one that never existed, so a sudden invalid_token on an OAuth connector token usually means “refresh, then retry.” Uninstalling the app also invalidates the shop’s tokens; reinstall to restore access. Each one returns the API’s standard error shape:

{
  "error": {
    "type": "authentication_error",
    "code": "token_revoked",
    "message": "This token was revoked. Create a new one in Settings → MCP & API Access."
  }
}

insufficient_scope adds a details object naming the token’s scope and the required one:

{
  "error": {
    "type": "permission_error",
    "code": "insufficient_scope",
    "message": "This token has the `read_experiments` scope. This request needs `write_experiments`.",
    "details": { "required_scope": "write_experiments", "token_scope": "read_experiments" }
  }
}

A 403 can also mean your plan doesn’t include the test type you asked for. Those errors share the permission_error type but carry different codes. See Feature availability.
