Gmail

Node catalog Actions

On this page

Search, read and send Gmail messages, manage labels and trash.

Usage and specifics

Select a Gmail OAuth credential authorized for the operation. Use query and pagination to list messages; supply recipients and content to send. Check labels and permissions before modifying messages.

Technical type : gmail. Runtime : nodulz.

Credentials and prerequisites

Gmail (integration / gmail). Google OAuth access to your Gmail mailbox with automatic token renewal.

Create credentials in your nodulz instance’s Credentials area, then select them on the node. Availability depends on ownership and sharing. See the credentials guide for access and rotation.

Verification

Test with representative data. Check node output in the inspector and logs, then use editor mapping for downstream fields. A trigger test with a simulated payload does not validate external service delivery.
