Step 1: Create a Workflow

  • To begin, access your Pabbly Connect account, proceed to your Dashboard, and initiate the process by creating a new workflow.

For the next phase of our process, we will skip the trigger step and move forward directly to the action step. By skipping the trigger stage, we eliminate the need for a specific event or condition to initiate the workflow. This allows us to simplify the process and proceed directly to the prescribed action without any external triggers.

Step 2: Add API Endpoint

  • In the Choose App field, select the API by Pabbly app. This app is specifically designed for integrating APIs into your workflows. By choosing this app, you will have access to the Web API, which will enable you to perform various PDF processing tasks.
  • In the Action Event field, choose POST. This method is commonly used when you want to send data to a server or create a new resource on the server. By selecting POST, you will be able to send the necessary information to the Web API for merging PDF documents.
  • For the Endpoint URL field, enter the following URL: This URL specifies the endpoint of the Web API that is responsible for merging PDF documents.
  • In the Payload Type field, select JSON type. This indicates that the data you will be sending to the API will be in JSON format.
  • In the Authentication field, select the No Auth. This means that no authentication or authorization is required to access the Web API for the merging process.

Add API Endpoint

Step 3: Setup Headers and Parameters

Let’s configure the Headers and Parameters.

  • In the Add Headers section, fill in the initial Label with x-api-key and insert your API key as the corresponding Value. This API key can be acquired either from your dashboard or by registering through this link. Next, for the second Label, type Content-Type and input application/json as the Value.
  • In the Add Parameters section, designate the first Label as url and provide the PDF URLs you wish to merge into a single PDF, separated by commas, as the corresponding Value. For the second Label, use async and set the Value as true. You can check out the API Docs for more information.
  • To conclude, click the Save & Send Test Request button, initiating a test of the workflow’s functionality.

Setup Headers and Parameters

Step 4: Send Test Request Result

  • The test generated successful results, and a response was received from Let’s move forward with incorporating the Pabbly Delay feature. Imagine if your file takes longer than 5 minutes to process. This delay ensures a sufficient amount of time for the processing to finish.

Step 5: Add Delay by Pabbly

  • During this stage, we will integrate the Pabbly Delay feature, allowing the file processing adequate time for completion.
  • Following this, select for the Delay For choice to hold off for a predetermined duration before finalizing your Actions.
  • Subsequently, choose for the Minutes as the chosen unit of delay.
  • Finally, input a delay value exceeding 5.

Once your done adding the delay, click on the Save and Send Test Request to ensure that it has been set up correctly.

Step 6: Add API by Pabbly

  • Within the Choose App field, select the API by Pabbly application. This application is purpose-built for seamlessly integrating APIs into your workflows.
  • For the Action Event field, choose for POST. This method finds common usage when you intend to dispatch data to a server or generate a new resource on the server.
  • In the Endpoint URL field, input the following URL:
  • In the Payload Type field, designate JSON as the format.

Step 7: Headers and Parameters Configuration

Let’s set up the Headers and Parameters configurations.

  • In the Add Headers section, label it as x-api-key and input your API Key as the value.
  • In the Add Parameters section, label it as jobid and input the jobId value derived from the response of the PDF Merger API.

Headers and Parameters Configuration
After setting up the configuration, test the workflow to see the result.

Step 8: Job Check Result

  • has effectively processed our request and verified the Job ID. You can proceed to copy the resulting URL and then paste it into your browser to view the merged PDF documents.

Step 9: Merge PDF Documents Output

  • Here is the merged PDF document obtained from the combination of multiple large files.

In this tutorial, you have learned about merging large files by utilizing the collaborative potentials of and Pabbly Connect. You’ve discovered the method to incorporate a time delay into the workflow to accommodate processing completion. Additionally, you’ve familiarized yourself with the procedure of verifying the JobID, an exclusive identifier for a specific PDF processing task initialized through their API.
