How to connect ConvertAPI and Formstack
Create a New Scenario to Connect ConvertAPI and Formstack
In the workspace, click the “Create New Scenario” button.

Add the First Step
Add the first node – a trigger that will initiate the scenario when it receives the required event. Triggers can be scheduled, called by a ConvertAPI, triggered by another scenario, or executed manually (for testing purposes). In most cases, ConvertAPI or Formstack will be your first step. To do this, click "Choose an app," find ConvertAPI or Formstack, and select the appropriate trigger to start the scenario.

Add the ConvertAPI Node
Select the ConvertAPI node from the app selection panel on the right.

Set Up the ConvertAPI and Formstack Integration
Use various Latenode nodes to transform data and enhance your integration:
- Branching: Create multiple branches within the scenario to handle complex logic.
- Merging: Combine different node branches into one, passing data through it.
- Plug n Play Nodes: Use nodes that don’t require account credentials.
- Ask AI: Use the GPT-powered option to add AI capabilities to any node.
- Wait: Set waiting times, either for intervals or until specific dates.
- Sub-scenarios (Nodules): Create sub-scenarios that are encapsulated in a single node.
- Iteration: Process arrays of data when needed.
- Code: Write custom code or ask our AI assistant to do it for you.

Save and Activate the Scenario
After configuring ConvertAPI, Formstack, and any additional nodes, don’t forget to save the scenario and click "Deploy." Activating the scenario ensures it will run automatically whenever the trigger node receives input or a condition is met. By default, all newly created scenarios are deactivated.
Test the Scenario
Run the scenario by clicking “Run once” and triggering an event to check if the ConvertAPI and Formstack integration works as expected. Depending on your setup, data should flow between ConvertAPI and Formstack (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
Most powerful ways to connect ConvertAPI and Formstack
Formstack + ConvertAPI + Google Drive: When a new form is submitted in Formstack, the submission data is converted to a PDF file using ConvertAPI and then saved to a specified folder in Google Drive for easy access and record-keeping.
Formstack + ConvertAPI + PandaDoc: When a new form submission is received in Formstack, ConvertAPI converts the submission data to a PDF document, and then PandaDoc creates a document from a template, attaching the generated PDF for signatures.
