How to connect Amazon S3 and OCR Space
Create a New Scenario to Connect Amazon S3 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 Amazon S3, triggered by another scenario, or executed manually (for testing purposes). In most cases, Amazon S3 or OCR Space will be your first step. To do this, click "Choose an app," find Amazon S3 or OCR Space, and select the appropriate trigger to start the scenario.

Add the Amazon S3 Node
Select the Amazon S3 node from the app selection panel on the right.

Configure the Amazon S3
Click on the Amazon S3 node to configure it. You can modify the Amazon S3 URL and choose between DEV and PROD versions. You can also copy it for use in further automations.
Add the OCR Space Node
Next, click the plus (+) icon on the Amazon S3 node, select OCR Space from the list of available apps, and choose the action you need from the list of nodes within OCR Space.

Authenticate OCR Space
Now, click the OCR Space node and select the connection option. This can be an OAuth2 connection or an API key, which you can obtain in your OCR Space settings. Authentication allows you to use OCR Space through Latenode.
Configure the Amazon S3 and OCR Space Nodes
Next, configure the nodes by filling in the required parameters according to your logic. Fields marked with a red asterisk (*) are mandatory.
Set Up the Amazon S3 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 Amazon S3, 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 Amazon S3 and OCR Space integration works as expected. Depending on your setup, data should flow between Amazon S3 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 Amazon S3 and OCR Space
Amazon S3 + OCR Space + Google Sheets: When a new file is added to an Amazon S3 bucket, the file (presumably an invoice) is sent to OCR Space to extract the text. Then, the extracted text data is added as a new row in a Google Sheets spreadsheet for accounting purposes.
OCR Space + Amazon S3 + Slack: When OCR Space converts a scanned document into text, the resulting text file is stored in an Amazon S3 bucket. After the file is uploaded to S3, a message is sent to a designated Slack channel to notify users that the conversion is complete and the file is available.
