Token

To authenticate requests, the Blink API uses an api_key and secret_key combination, which is used to obtain an access_token for your session.

HTTP Basic Auth is used for authentication. The access_token should be used via bearer in the header to authenticate all requests, e.g. Authentication: Bearer {{access_token}}.

Access token is expired after 30 minutes. Then, you need to call refresh token request to regenerate the token.

You can manage and renew your keys on the Blink platform. In case you do not see the keys, simply reach out to support to get set up.

It is essential to keep your API keys secure as they hold significant privileges. Refrain from sharing your secret API keys in public areas such as GitHub, client-side code, etc.

All API requests must be made over HTTPS. Requests made over plain HTTP will be unsuccessful. API requests that lack authentication will also fail.
