When wiring an external integration to Coralogix, generate or copy the key from the Send Your Data flow, not from a random API keys page. If the integration rejects your key or data never arrives, confirm which Coralogix key you used before debugging anything else, because the wrong key type fails without a helpful error.

Context: Control Plane external logging docs for Coralogix document the key-selection mistake that produces silent auth failures. The integration requires the Send Your Data API key specifically, not any arbitrary Coralogix key, so pasting a key from another section of the Coralogix settings never authenticates even though it looks valid.
