API Development and Integration in Bangladesh

Connect a defined business workflow

An integration is useful when one system needs information or an action from another: a website sends an order, a staff workspace receives a status update, or an app reads the customer’s records. The first decision is which system is authoritative for each record.

Okriya can scope APIs for a new application and connections between existing systems as part of custom software development. Possible scopes include an app backend, an order-status connection or a controlled data import. These are examples to discuss, not a claim that every third-party system is accessible.

For a Bangladesh project, identify the local services you need to connect and whether your business has the necessary account and API access. Provider approval, documentation and test environments are dependencies to confirm before committing to a delivery date.

What we need to scope the connection

1. The business event: what starts the exchange, who needs the result and how quickly it is needed.
2. The systems: provider names, available API documentation, test access and the person responsible for each system.
3. The data: sample records with sensitive information removed, identifiers, required fields, status values and expected volume.
4. The direction: one-way or two-way updates, which system wins if values differ and which records must never be overwritten.
5. The operating rules: access restrictions, retention expectations, provider limits and who investigates failures.

A request such as “sync our orders” needs those details. A completed order, a cancelled order and an edited order may each need different handling.

Define the API and integration deliverables

Credentials should be shared through an agreed secure access process, not pasted into a project brief. Separate test and production access and identify who can revoke or rotate it. Permission checks must apply to the records an account is allowed to access, not just whether it is signed in.

If the project also needs screens for staff to review failed records, correct mappings or trigger a retry, include that web application scope. An API connection alone does not provide an administration interface.

Plan for failures and duplicate events

External systems can respond slowly, reject a record or send an event more than once. Decide which failures can be retried, when a person should investigate and how duplicate processing is prevented. A retry that creates a second order is not a successful recovery.

Define a reconciliation check: for example, compare the source order identifier with the destination record and flag missing or inconsistent statuses. Logs should help the team investigate without unnecessarily exposing customer information or credentials.

Agree an alert owner and a manual fallback when appropriate. If the provider changes an API, expires credentials or limits access, someone must be responsible for reviewing the impact. Include those responsibilities in the support arrangement.

Test the connection before production

• Confirm correct field mapping and expected results for representative records.
• Check missing fields, invalid values, denied access and inaccessible records.
• Test repeated events, timeouts and temporary provider failures.
• Review reconciliation, failure visibility and any agreed retry tools.
• Validate historical imports separately from ongoing updates.
• Document deployment, credential ownership, rollback and support contacts through the agreed private handover.

Ask a proposal to separate development from provider fees, usage charges, infrastructure and ongoing monitoring. If a packaged product can already handle the workflow, the custom versus off-the-shelf guide can help you decide how much new development is worthwhile.
