Get in touch

Reach the Grand team at support@heygrand.com for technical questions and bug reports. For credentials, rate-limit increases, and commercial questions.

Before you reach out

To help us resolve your issue quickly, include:

  • What you called — the endpoint, HTTP method, and (redacted) parameters.
  • What you got back — the HTTP status code and the response body's message.
  • When it happened — an approximate timestamp and timezone.
  • What you expected instead.

Never share your client_secret or a live access_token in an email or ticket. If you believe a secret has been exposed, tell us immediately so we can rotate it.

Common questions

My token stopped working after an hour. That's expected — tokens last one hour and there's no refresh token. Request a new one. See Authentication.

Search returns nothing for a company I know exists. Check the jurisdiction (GB vs IE) and try a more specific name. See Jurisdictions.

I'm getting 429 responses. You're exceeding your rate limit. Back off and retry, and cache your access token. See Rate limits.
