You need a compliant Data Provider (issuer) API that APISetu's gateway can call on behalf of authorised consumer apps to verify and pull your PDFs. I'd implement the standard pull flow — a verification endpoint that confirms a document exists for the given CertificateParameters, and a pull endpoint that returns the base64 PDF inside the mandated XML/JSON envelope — with HMAC/consumer-key validation, txnId echo, correct error codes, and rate-limit-safe handling. PDFs get normalised server-side: A4 orientation, application/pdf MIME, size kept under the gateway ceiling, optionally PKCS#7 signed so they verify in Adobe. You'll get a staging URL, Postman collection, .env reference and setup notes for your MeitY paperwork. I can start immediately.

Hi, I can create a reliable document-sharing API focused on PDF files for the APISetu platform. I understand the importance of seamless integration with APISetu’s workflow, ensuring that authorized consumer applications can easily request, fetch, and display your organization’s PDFs. To address the project challenge, I will build and expose the necessary endpoints for publishing documents, fetching them on demand, and checking their status. I will ensure compliance with the standard consent, token, and callback sequence mandated by APISetu, facilitating straightforward onboarding with MeitY. I will handle PDF formatting nuances, including page orientation, file size limits, and MIME types, ensuring that every file returned is immediately usable. Additionally, I will provide concise setup notes, Postman collections for quick testing, and a small read-me outlining any required environment variables or secrets. I have successfully delivered similar APISetu integrations in the past, and I can have a staging version ready within 10 days to initiate the compliance paperwork. Ready to start immediately!

@gotucat

Hi, I reviewed your request to build an APISetu PDF Sharing API that lets authorised consumer applications request, fetch, and display organisation PDFs in the same flow as DigiLocker-style services. I’ll design the publishing, fetching, and status-check endpoints, then implement the consent, token, and callback sequence mandated by APISetu so onboarding later with MeitY stays straightforward. I’ll also normalize PDF formatting nuances like orientation, file size limits, and correct MIME types to ensure responses are immediately usable without post-processing, and I’ll validate everything with API Testing and clean Software Development practices. You’ll get clear setup notes, a Postman-ready collection for quick testing, and a concise read-me for environment variables. Let’s discuss here now.

@AndrewJSMAN

I’ve integrated APISetu’s document-sharing flows for two state nodal agencies last year, handling consent, token exchange, and callback validation—so this is right in my wheelhouse. I’ll scaffold a minimal REST API in Node.js with Express, wiring the three mandatory endpoints (publish, fetch, status) to APISetu’s OAuth2 and callback endpoints using their exact payload schemas. PDF handling sits behind a lightweight Sharp pipeline that enforces size limits, correct MIME types, and retains original page orientation without post-processing. A single Postman collection with preconfigured auth will let you hit the staging URL the same afternoon; I’ll drop a one-page README with environment variables and secrets placement only. Staging build ready in three days. Thanks, Andrii.

@mickeysz

Hello, The heart of an APISetu integration is not the PDF handling, it is becoming a compliant document repository, which is what decides MeitY onboarding. As a publisher, your API implements the roles APISetu expects: an endpoint declaring what identifiers locate a document, and a pull-document endpoint returning the file only against a valid, consented request. The consent, token, callback sequence you named is the core, and the detail that matters is that every fetch verifies the request came through APISetu with a valid token before releasing anything. A repository that returns a PDF without validating the token fails certification and leaks documents. So verification first, file second. On the PDF, APISetu expects it base64-encoded with the correct MIME type, within the size limit. So I fetch or generate, confirm a valid single PDF of the right orientation, and encode it so the consumer app renders it directly, no post-processing, as you want. On your optional ideas, digital signatures genuinely add value: a signed PDF lets the receiving app verify authenticity, the whole point of a DigiLocker flow. I would build so signing slots in naturally. I deliver a staging endpoint, a Postman collection covering the full consent-to-fetch sequence, and setup notes listing every secret and variable, so you start the paperwork against a working reference. One question: are the PDFs pre-existing files you store, or generated per request from live data? That shapes the design.

@naminghn

Hi there, I can build the document-sharing API you need for APISetu, ensuring it integrates seamlessly with the existing workflow. I have experience developing RESTful APIs and can handle the required endpoints for publishing and fetching PDFs, while adhering to the consent, token, and callback standards specified. For the PDF nuances, I'll make sure to address page orientation, file size limits, and MIME types appropriately. I can also provide concise setup notes and Postman collections for quick testing. Kindly share any specific deadlines you have in mind, and I'll get started promptly. Your satisfaction is my priority and I guarantee that I will deliver you a high-quality result. Regards, Ali

@tyronet2

APISetu integration needs more than serving PDF files; the issuer API, consent flow, credentials, document metadata and audit trail must align with onboarding requirements from the beginning. I’ll first map your document types and existing storage against APISetu’s publisher workflow, then implement versioned endpoints for document discovery, retrieval and status. The service will validate consent and tokens, secure callbacks, record access events and return consistent metadata, MIME types and error responses. PDFs will be checked for size, orientation, readability and integrity before delivery, with optional encryption or signing added only where the approved workflow supports it. A staging deployment, automated tests, Postman collection, environment template and concise README will be included. Which organisation type, document category and APISetu onboarding stage are you currently at?

@denisSolution

Hi, I’m Denis and have worked with government-approved API platforms like APISetu for secure document exchange. I understand you need a clean REST API that exposes endpoints for publishing PDFs, fetching them securely, and tracking status—exactly matching APISetu’s consent and callback flow so your MeitY onboarding stays simple. The core challenge is making sure every PDF returned is immediately usable—handling file size, orientation, and MIME types without extra processing on the consumer side. I’ll keep the API lean but robust, include Postman collections for quick testing, and document every environment variable so your team can move straight into compliance paperwork. Similar integrations I’ve built required strict OAuth sequences and status callbacks, and those systems stayed stable under high concurrent loads. Staging can be live within a week so you can begin validation right away. I can start working right away. Let's connect and discuss the details. Thanks, Denis.

@Eliteinno

Hello, The critical part of this integration is reproducing APISetu's expected consent, token, callback, and document retrieval flow correctly, rather than exposing a generic PDF REST API. The implementation should also keep PDF validation separate from the API layer so MIME type, file size, orientation, and delivery issues can be tested independently. I would structure the staging version around clear environment configuration, reproducible Postman tests, callback logging, and failure handling so the compliance workflow can be validated before production onboarding. Are you already registered with APISetu and have access to the relevant sandbox specifications and credentials, or does the project include obtaining those prerequisites? Have a nice day

@longngoc2307

==== Hi - Truong here ==== "APISETU PDF DOCUMENT SHARING API" — you need the consent, token, callback, and PDF delivery flow working correctly for compliance and staging. I’d keep the API focused on APISetu’s required publish, fetch, and status flow, with strict PDF MIME/type and size validation before any document is returned. I’ll also provide Postman tests and a short setup guide so the staging environment is easy to verify. Which APISetu onboarding documentation or sandbox credentials will you provide for the required consent and callback flow?

@AneesaIBA

Hello, I have carefully read your project description and understand that you are looking for a skilled professional to develop a reliable PDF document-sharing API integrated with the APISetu platform, following its consent, authentication, token, callback, and document-fetching workflows. To approach your project I will first review the APISetu integration requirements and design a secure, versioned REST API for document publishing, retrieval, status checks, and authorised access. I’ll handle PDF validation, MIME types, file-size limits, orientation and secure storage while ensuring the response format is immediately usable by consuming applications. I’ll also prepare Postman collections, environment configuration, authentication secrets, error handling, logging, and clear documentation to make staging and subsequent MeitY onboarding straightforward. Digital signatures or encryption can be considered where they provide genuine value. In terms of relevant experience, I have experience developing secure REST APIs, authentication flows, document-processing systems, third-party API integrations, and production-ready backend services. I’d love to discuss your APISetu requirements further and review any existing documentation or sandbox access you have. Best Regards, Rabia Shaikh.

@melopgabriel

Hi, your APISetu PDF sharing flow is clear: you need a compliant document API that lets authorised apps request, fetch, and display PDFs reliably. I’ve built integration-heavy APIs with consent, token, and callback sequences, and I’m comfortable working with PDF delivery rules, MIME handling, file limits, and response validation. I’d focus first on the APISetu contract, then implement the publish, fetch, and status endpoints so the workflow is stable and easy to onboard later with MeitY. I’d also prepare Postman collections, concise setup notes, and a small read-me covering environment variables, secrets, and testing steps. If encryption or digital signatures fit the flow, I can include them without adding unnecessary complexity. I can have a staging version ready quickly so you can begin compliance paperwork with confidence. Best regards, Gabriel
