If you need to get specific coordinates in PDF, you can use this simplified PDF Viewer tool. It is available with PDF.co Web API and its integrations.
On-Premise for Enterprise
PDF.co platform works on secure and certified cloud infrastructure. Enterprise customers can process sensitive data in-house using our on-premise version. It works on your server and can even run completely offline when required.
PDF Editor API Sample & Demo
For this demo, I am going to use a Sample PDF File.
The code snippets used below can be written in different programming languages. The Web API engine adds text to our sample PDF file. The final result will look like this.
Before we proceed with the code. Let us first check the /v1/pdf/edit/add parameters and its uses.
Endpoint
| URL: | https://api.pdf.co/v1/pdf/edit/add |
| Method: | POST |
| Parameter | Description |
| url | required. Link to the source file. |
| annotations[] | optional. An array of text objects to be added on top of pdf. Text objects can be ready-only ("type": "text" by default), input pdf input fields ("type": "textField") or checkboxes ("type": "checkbox"). See font list for all PDF.co supported fonts. |
| images[] | optional. An array of image URLs (also can be a link to Files storage or Datauri link) to be added on top of the PDF file. Images can be loaded from URLs or URLs for internal file storage. |
| fields[] | optional. An array of values to update fillable pdf fields in input pdf. You can create your own automated PDF filler for your pdf forms using this array. |
| password | optional. The password of the PDF file. Must be a String. |
| async | optional. Runs processing asynchronously. Returns Use JobId that you may use with /job/check to check the state of the processing (possible states: working, failed, aborted and success). Must be one of: true, false. |
| encrypt | optional. Enable encryption for the output file: true or false |
| name | optional. Output file name. |
| profiles | optional. Must be a String. Set custom configuration. See profiles examples here |
Now we are ready to write some codes.
