How to connect Postmark and OCR Space
Create a New Scenario to Connect Postmark and OCR Space
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 Postmark, triggered by another scenario, or executed manually (for testing purposes). In most cases, Postmark or OCR Space will be your first step. To do this, click "Choose an app," find Postmark or OCR Space, and select the appropriate trigger to start the scenario.

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

Set Up the Postmark and OCR Space 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 Postmark, OCR Space, 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 Postmark and OCR Space integration works as expected. Depending on your setup, data should flow between Postmark and OCR Space (or vice versa). Easily troubleshoot the scenario by reviewing the execution history to identify and fix any issues.
Most powerful ways to connect Postmark and OCR Space
Postmark + OCR Space + Google Sheets: When a new email arrives in Postmark, the attached invoice image is processed by OCR Space to extract the text. The extracted data is then added as a new row in Google Sheets for accounting purposes.
Postmark + OCR Space + Slack: When a new email arrives in Postmark, its attached document is sent to OCR Space for text extraction. If the extracted text contains a specified critical term, the document is emailed, and a Slack message is sent to a designated channel.
