Save yourself the work of writing custom integrations for Missive and Postgres and use n8n instead. Build adaptable and scalable Communication, Development, and Data & Storage workflows that work with your technology stack. All within a building experience you will love.
Step 1: Create a new workflow and add the first step
In n8n, click the "Add workflow" button in the Workflows tab to create a new workflow. Add the starting point – a trigger on when your workflow should run: an app event, a schedule, a webhook call, another workflow, an AI chat, or a manual trigger. Sometimes, the HTTP Request node might already serve as your starting point.
Step 2: Add and configure Postgres and Missive nodes (using the HTTP Request node)
You can find the Postgres node in the nodes panel and drag it onto your workflow canvas. To add the Missive app to the workflow select the HTTP Request node and use the generic authentication method to make custom API calls to Missive. Configure Missive and Postgres one by one: input data on the left, parameters in the middle, and output data on the right.
Step 3: Connect Postgres and Missive
A connection establishes a link between Postgres and Missive (or vice versa) to route data through the workflow. Data flows from the output of one node to the input of another. You can have single or multiple connections for each node.
Step 4: Customize and extend your Postgres and Missive integration
Step 5: Test and activate your Missive and Postgres workflow
Save and run the workflow to see if everything works as expected. Based on your configuration, data should flow from Missive to Postgres or vice versa. Easily debug your workflow: you can check past executions to isolate and fix the mistake. Once you've tested everything, make sure to save your workflow and activate it.
Build your own Missive and Postgres integration
Create custom Missive and Postgres workflows by choosing triggers and actions. Nodes come with global operations and settings, as well as app-specific parameters that can be configured. You can also use the HTTP Request node to query data from any app or service with a REST API.
Supported API Endpoints for Missive
To set up Missive integration, add the HTTP Request node to your workflow canvas and authenticate it using a generic authentication method. The HTTP Request node makes custom API calls to Missive to query the data you need using the API endpoint URLs you provide.
