Activate card

POST /v2/api-gateway/cards/{card_id}/activate

Activates the card. Returns 200 (not 201) with { message }.

Request

Authentication: your API key in the x-api-key header.

Path parameters

Field	Type	Description
`card_id` required	string, uuid	Card UUID (the card `id` returned by the card endpoints).

Headers

Field	Type	Description
`Idempotency-Key`	string	A unique string you choose, up to 255 characters, that makes this request safe to retry. If a request times out or fails in transit, send it again with the same key: the status code and body of the first attempt are returned and the operation is not performed a second time. Stored replies — including failures — are replayed for 24 hours, after which the same key starts a fresh request. Reusing a key for a different request, or sending it while the first request is still running, returns 409. Omit the header and the request behaves exactly as before. Document upload endpoints do not accept it.

Example request

cURL

curl --request POST \
     --url 'https://api.themooncard.com/v2/api-gateway/cards/7c9e6679-7425-40de-944b-e07fc1f90ae7/activate' \
     --header 'x-api-key: YOUR_API_KEY'

Responses

200 Success

Field	Type	Description
`message` required	string	Human-readable confirmation of what happened. The wording is fixed per route — the response description on each operation quotes it — but it is not a stable machine key: branch on the 2xx status, not on this text.

JSON

{
  "message": "Card with ID 7c9e6679-7425-40de-944b-e07fc1f90ae7 activated successfully."
}

400 Error

Validation failed (errors[] lists each offending field) or a domain rule rejected the request ({ message, code }).
