Build with AI 2 packages

A build package is every page for one task, with the API operations they use. Copy the prompt into a coding assistant, or hand it the package itself: slim links to each page, full inlines all of them in one document.

Take a paymentEverything needed to take a payment end to end with One API, from credentials through the hosted page to the webhook that confirms it, and the test cases that prove each outcome before you go live.

X-Correlation-ID header
The correlation id for the request that was processed.

links PaginationLinks
Standard JSON API pagination links. Each link repeats the query that produced the collection and carries its own limit and offset. Follow the link rather than building the next URI. The example below is the second of three pages.
Fields of PaginationLinks
- self string uri
  The current page of data.
- first string uri
  The first page of data.
- last string uri nullable
  The last page of data. Null when the whole collection fits on one page.
- prev string uri nullable
  The previous page of data. Null on the first page.
- next string uri nullable
  The next page of data. Null on the last page.

results array of WebhookResponse
Fields of WebhookResponse
- id string uuid required
  The unique identifier of the webhook.
- endpoint string uri required
  The uri of the webhook receiver.
- eventType string required
  The type of event the webhook subscribes to.
  values"transaction.complete""refund.complete"
- messageType string required
  Defaults to thin. Specify full to receive a larger payload with as much detail as possible.
  values"thin""full"

400 Bad Request.

X-Correlation-ID header
The correlation id for the request that was processed.

id string uuid required
a unique identifier for this particular occurrence of the problem.
links object nullable
Present on an authentication or authorisation failure, and null otherwise.
- about string uri
  A link that leads to further details about this particular occurrence of the problem. When derefenced, this URI SHOULD return a human-readable description of the error.
- type string uri
  A link that identifies the type of error that this particular error is an instance of. This URI SHOULD be dereferencable to a human-readable explanation of the general error.
code string required
An application-specific error code, expressed as a string value. Key on this rather than on title or detail, which are written for a person. A rejection at the transport level uses the status name, one of BadRequest, Unauthorized, Forbidden, NotFound, NotAllowed, Conflict, UnsupportedMediaType, BadGateway or InternalServerError. An operation refusing a request on its own rules returns a code of its own.
title string required
A short, human-readable summary of the problem that SHOULD NOT change from occurrence to occurrence of the problem, except for purposes of localization.
detail string required
A human-readable explanation specific to this occurrence of the problem. Like title, this field’s value can be localized.
source object nullable
Where in the request the problem was found. All three keys are present whenever source is, with the ones that do not apply set to null. source itself is null where the failure is not about a part of the request.
- pointer string json-pointer nullable
  a JSON Pointer RFC6901 to the value in the request document that caused the error [e.g. "/data" for a primary data object, or "/data/attributes/title" for a specific attribute]. This MUST point to a value in the request document that exists; if it doesn’t, the client SHOULD simply ignore the pointer.
- parameter string nullable
  A string indicating which URI query parameter caused the error.
- header string nullable
  A string indicating the name of a single request header which caused the error.
meta object nullable
A meta object containing non-standard meta-information about the error. Null where the request carried no X-Correlation-ID, and on an authentication failure, which does not echo it.
- correlationId string
  The X-Correlation-ID sent with the request, echoed back so it can be quoted to support. Absent when the request carried no correlation header.
