API integration services in India

Check for an official connector first. An existing integration may cover the connection you need without custom code. Where you need a custom connection, direct links work well when only a few systems are involved. As you add systems, a central integration service can make the connections easier to manage than a growing network of links between individual products.

Then decide how information should travel. A one-way sync is simpler and safer. A two-way sync needs rules for resolving a record changed in both systems. Webhooks keep data current, but need a reachable endpoint and a way to handle duplicate events; scheduled batches are simpler and suit reporting or overnight updates.

A missing API does not necessarily stop the work: we can often use an export or email instead. We handle design, development and launch in the same team, so you can discuss the choice with the people responsible for the build.

If your business falls within GST e-invoicing requirements, invoice fields need to match across the systems involved. We map differences in IDs, formats and tax codes, including what happens when a record exists in only one system, before setting up the flow.

Some businesses also have a deadline for reporting e-invoices to the Invoice Registration Portal. For an applicable invoice flow, we set up scheduled data sync with error handling, logs and alerts, so your team can see a failed transfer and act on it.

Bring what you have available; it will help us establish the scope and identify access gaps.

• List the systems and their plans or editions, including whether API access is included.
• Identify admin access or API credentials under business-owned service accounts, plus sandbox accounts where available.
• Collect sample records and examples of awkward cases your team currently handles by hand.
• Decide who should receive a failed-sync alert and how quickly someone needs to act.
• Identify an owner for API keys or OAuth tokens, and plan for secure storage and renewal before expiry.

  Unclear ownership of data

  Agree which system holds the authoritative value, or a two-way sync can overwrite good information with stale data.

• !

  Assuming webhook delivery order

  Events can arrive twice or out of order. Log processed event IDs and avoid building rules that depend on their delivery order.

• !

  Using a personal login

  Credentials tied to an employee can stop working when they leave. Use service accounts owned by the business.

  Missing a failed sync

  Set up alerts and assign someone to act, so missing orders or invoices do not go unnoticed.
