The Procuros API uses API tokens to authenticate requests. Please contact [email protected] to request an API token.

In order to perform an authenticated request, use the Authorization header to provide your API token as a "bearer token" like this: Authorization: Bearer <YOUR-API-TOKEN>.

All requests to all endpoints of our API have to be made using the above authentication method. Unauthenticated calls will fail with a 401 status code.

Testing your Connection

Below are examples of how to ping the API to ensure your credentials are correct.

If you get a successful response from the enpoint, your authorization is confirmed. If you receive a 401 Unauthorized error then your API key is not correct for this environment.

curl --request GET \
     --url '' \
     --header 'Accept: application/json' \
     --header 'Authorization: Bearer <YOUR-API-TOKEN>'
$client = new \GuzzleHttp\Client();
$client->request('POST', '', [
  'headers' => [
     'Accept' => 'application/json',
     'Authorization' => 'Bearer <YOUR-API-TOKEN>'

$response->getStatusCode(); // => 200

SSL Encryption

Requests to the Procuros API can only be made over HTTPS. Unsecured requests using HTTP will fail.
