Apply to become a Grubhub integration partner at developer.grubhub.com; partner approval is required before API access is granted
Authenticate using OAuth 2.0 client credentials to obtain a bearer token for subsequent API calls
Submit the initial menu payload using the menu creation endpoint; the payload must include items, modifiers, hours, and price information in the Grubhub schema

Test integration end-to-end in the Grubhub sandbox environment before requesting production activation
Known gotchas
Menu management via the API is required, not optional, for integrated partners; failing to keep the Grubhub menu in sync leads to customer complaints and potential order issues
Grubhub's Onboarding API supports self-service merchant activation; if your integration bypasses it, manual Grubhub onboarding takes 7-10 days instead of minutes
Price discrepancies between your POS menu and the Grubhub menu are the most common cause of order disputes; automate sync rather than relying on manual updates
