Authentication

Authorizationstring

Every request made to https://api.uploadcare.com/ MUST be signed. HTTPS SHOULD be used with any authorization scheme.

Requests MUST contain the Authorization header defining auth-scheme and auth-param: Authorization: auth-scheme auth-param.

Every request MUST contain the Accept header identifying the REST API version: Accept: application/vnd.uploadcare-v0.7+json.

There are two available authorization schemes:

For production: Uploadcare, a scheme where a signature, not your Secret API Key MUST be specified. Signatures SHOULD be generated on backend.
For quick tests: Uploadcare.Simple, a simple scheme where your Secret API Key MUST be specified in every request’s auth-param.
