About Flexprice

Through Operate As, your agent, n8n workflow or code works in Flexprice with your client's own access. Your client pastes their API key from Flexprice once. We store it encrypted, so it never sits in an email or a shared doc. Your agent reaches any endpoint of Flexprice's API through the request tool, with the client's access attached.

Common uses in Payments
