Gmail and WhatsApp connectors

Shared by Pavel · Updated 2026-11-03

Gmail and WhatsApp were identified as first-class, pre-built Substrate connectors; the evidence establishes that they are supported sources, but does not establish their connection mechanics or implementation status.

What the evidence establishes

• Pavel described Substrate as pulling context from supported sources including Gmail and WhatsApp, while noting that the number of supported sources was limited.
• Gmail is identified as a source Substrate ingests; its access requires Google OAuth verification and a CASA assessment.
• Gmail can use Google Cloud Pub/Sub mailbox watches, with mailbox history and cursors supporting reconciliation. These are described capabilities, not proof that a specific Gmail connection was completed.
• WhatsApp was described as already live in Substrate on October 6, but no connection mechanism or implementation details were established.
• Separate WhatsApp group-chat references identify use of WhatsApp, but do not establish connector implementation.
