How APIs connect a publishing workflow

A custom publishing system is one example of API integration: connected accounts, queued tasks and reporting in one workflow. All screens, accounts and metrics are illustrative, not client results. Feasibility depends on platform access and project scope.

Process

Five stages, each with something you can accept

From access checks and API design to implementation, testing and handover, each stage has an agreed deliverable. Timing depends on interfaces, existing systems and third-party reviews.

Scoped per project

Scope & access

Confirm platforms, business actions, existing interfaces and account permissions before estimating the work.

Scoped per project

API & solution design

Agree requests, responses, field mappings, authorization, callbacks and acceptance samples.

Scoped per project

Build & integrate

Implement APIs, data synchronization and workflows with rate limits, retries and failure handling.

Scoped per project

Test & accept

Validate agreed accounts and business samples, with integration records and test documentation.

ongoing

Launch & care

Deploy to your environment, train your team, start the adaptation period.

Deliverables

What you get

✓ Custom source code and adapters within the agreed scope
✓ Request, response, authorization and error documentation
✓ Deployment guide and required runtime scripts
✓ Field mappings and integration notes
✓ Business samples and test records
✓ Operations handover and maintenance scope
Delivery

Milestone delivery

Each stage has a deliverable and an acceptance gate, defined before the next stage starts.

Why us

What matters in an API development project

01

Feasibility before implementation

Validate platform access, account conditions and business actions before agreeing scope and acceptance criteria.

02

Source and documentation together

Receive scoped custom code, API documentation and deployment materials. Third-party API charges and licenses are stated separately.

03

Results you can inspect

Use agreed samples to verify fields, callbacks and failures. Track interface acceptance separately from final business outcomes.

04

Compliance by design

No passwords, no bulk account creation, no fabricated data.

FAQ

Questions we get before a project

What determines API development cost and timing?

We assess interface count, business actions, platform access, data volume and existing systems before estimating design, implementation, testing and deployment. Project fees, third-party API charges and maintenance are explained separately. Platform review time is additional; a full system quote is not a single-interface estimate.

Can you build one API or integrate our existing software?

Yes. Start with a business interface whose access has been verified, connecting your existing dashboard, CRM, BI or content system as needed. Agree fields, authorization, callbacks and acceptance samples before extending the scope.

Where is it deployed, and who owns the data?

Self-hosted on your servers or cloud account, with the database, object storage and account credentials staying in your environment. A hosted option with tenant isolation is available. Delivered as Docker or K8s.

How do you handle account authorization and platform risk?

Through official platform authorization (OAuth, open-platform apps or QR authorization). No passwords, no simulated logins, no bypassing platform risk controls. Publishing uses rate limits, backoff and retries; restrictions and review failures are logged. Content violations can still be limited by the platform and are outside the system.

Where does the monitoring data come from?

We prefer platform APIs and public search results (Baidu, Bing, creator backends). Where those are unavailable, we use on-platform search and manual sampling. Each source is labeled separately in reports rather than blended into one number.

Do we own the source code?

We hand over custom source code, API documentation, integration notes and deployment materials within the agreed project scope. Third-party platforms, open-source components and API subscriptions retain their own licensing and charges.

What happens when a platform changes its API?

Minor changes are adapted free for 6 months after delivery (12 months for Enterprise). For major changes, such as removed capabilities or a new authorization system, we scope the work before starting.

Tell us what you need — we will scope it

Bring your target platforms, existing software and business actions. We will assess access, delivery scope and the factors behind cost and timing.
