TapScanner (pdf.tap.scanner) Data API

Tap AI · Utilities

Open on Google Play

PDF Scanner app - TapScanner is a camera-to-PDF document scanner and editor for Android from Tap AI: the camera screen photographs paper pages and saves them as PDFs, a text-recognition step sends a scanned page to the cloud and brings back its text page by page, and a PDF-to-DOCX converter turns a finished scan into an editable Word document. Premium features sit behind a paid tier that can also be unlocked with a promotional redeem code handed out through bundle partners and checked against the user's device. Listed under utilities, it serves mobile productivity users in the United States, India, Brazil and Indonesia who digitise contracts and other paperwork on their phones, and it competes with Adobe Scan, CamScanner, Genius Scan, Simple Scan, SwiftScan and Clear Scan as well as India's Kaagaz.

Recognition jobs are the core record here: a scanned page enters as a job reserved with an id and a pre-signed uploadURL, carries a status that reads ok when the slot is reserved, started once recognition begins and done when it finishes, and closes stamped with a startTimestamp, the recognized document text and a files list of per-page outputs, each retrievable on its own by fileName. Conversion adds a second document stream, in which a scanned PDF submitted as a file part comes back as an editable DOCX. A separate entitlement slice pairs a promotional redeemCode with a deviceId and answers with a verified flag.

Document-intake automation runs on that job lifecycle: back-office pipelines reserve an upload slot, start recognition and poll until status reads done, then land the text in a document-management system without anyone opening the app. Contract and legal tooling batch-converts scans from PDF to DOCX for redlining and collects the editable documents, and bundle partners check a redeemCode against its deviceId before granting premium features, so every promotional license traces back to one device. openData Studio turns these recognition jobs, PDF-to-DOCX conversions and redeem-code checks into callable open data.

Frequently asked questions

How does TapScanner's server-side text recognition pipeline work?

Recognition runs as a job pipeline over three calls: POST /v1/jobs/prepare reserves an upload slot and returns a job id plus a pre-signed uploadURL, POST /v1/jobs/{id}/begin starts recognition on the uploaded scan, and POST /v1/jobs/{id}/result is polled until the status is done, returning the recognized text and the files list of per-page outputs.

How are TapScanner's API calls authenticated?

Every recognition and conversion call carries an integrity_token request header holding a Google Play Integrity token; there is no session cookie or bearer token in the flow. The one exception is POST /v1/licenses/redeem, which is gated only by the redeemCode and deviceId pair in its JSON body.

What fields does the recognition result return?

The POST /v1/jobs/{id}/result response carries status, startTimestamp, files (a list of per-page output files) and text (the recognized document text). Individual pages are then downloaded via GET /v1/jobs/{id}/artifacts/{fileName}.

How does TapScanner convert a scanned PDF to DOCX?

The app uploads the scanned PDF to POST /v1/convert/office as multipart form data with a single file part, authenticated by the same integrity_token header, and the service streams back the converted DOCX document as a binary response body.
