This instance couldn't reach its API specification on the last attempt, so this page shows the copy fetched before that. Anything added or changed since then is missing here, and the reference updates itself as soon as the specification is readable again. Last fetched 2026-11-12 05:58 UTC.
API reference

Merchants
Counts the Merchants that match a filter.
POST
/api/merchants/list/continuation/count
deprecated
Requires: Merchants.MerchantRead, merchant scope.
Requires API key scope:
admin
(Administration)
Takes the same request body as the continuation list endpoint and returns how many
Merchants match it, without returning the records themselves. The count is
approximate and is intended to sit alongside a paged list, so treat it as a display
figure rather than a reconciliation total.
Signed in, you can send this request to your own sandbox merchant from the console
and read the answer.

Example request
Every block below sends the same request. Replace {{BASE_URL}} with the address of the API you are calling and {{API_KEY}} with your own key.
The request body is a GetMerchantsContinuationInput. See the Request body section below for its fields.

Too Many Requests
The request was refused because a rate limit was exceeded, or because something a later retry can clear stopped it. A rate limit refusal carries an `application/problem+json` body: wait at least the interval `Retry-After` names before retrying, then back off. Limits are tuned per deployment, so read the allowance from the response headers rather than assuming a fixed ceiling. Any other refusal carries the standard error envelope as `application/json`, and its `error.code` names the cause.

Errors
400 401 403 404 500 501 default
400
Bad Request
Bad request. The request was malformed or failed validation. When validation rejected it, `error.validationErrors` names each member at fault and why. 401
Unauthorized
Unauthorized. The request carried no API key or signed-in session, or the key it carried is invalid, revoked or expired. 403
Forbidden
Forbidden. The API key lacks the scope this operation needs, the signed-in user lacks the permission, or a business rule refused the request. The error code in the body names the reason. 404
Not Found
Not found. The resource the request names does not exist or is not visible to the caller: a resource that belongs to a merchant or tenant outside the caller's scope is reported as not found. 500
Internal Server Error
Internal server error. The platform failed unexpectedly while handling the request. If it keeps failing, contact support and quote the correlation id, which the response carries in the `X-Correlation-Id` header and as `error.data.correlationId`. 501
Not Implemented
Not implemented. The operation is declared but has no implementation on this deployment, so no request to it can succeed. Retrying does not help. default
The request failed. The body carries the standard error envelope: a machine-readable `error.code`, a human-readable `error.message`, and `error.validationErrors` when the failure was a validation rejection. The error reference lists the values `error.code` can take. The request failed.
