In Omnisend, go to API keys or follow the help guide Generate an API Key in Omnisend. Click Create API key, name the integration, choose the needed permissions, then Create API key and copy the value immediately. Use it in the Authorization header as Omnisend-API-Key YOUR-API-KEY.
To get Omnisend OAuth client credentials for an app, submit the request form linked from the OAuth docs and Create your own app. Omnisend says it will reply with a client_id and client_secret in 1–3 business days. Use those to run the OAuth authorization-code flow against https://app.omnisend.com/oauth2/authorize and https://app.omnisend.com/oauth2/token, then send the resulting access token as Authorization: Bearer ....
Point your MCP client at the server URL and approve access in the browser. The server supports OAuth Dynamic Client Registration (RFC 7591), so the client registers itself automatically — no developer-portal app, client_id, or client_secret to create.
