What problems should this ability solve?

Introduces the API, Webhook, data synchronization, authentication, retries and logs, allowing the website to connect to CRM, ERP, logistics and business systems.

Key TakeawayThe focus of interface development is not “Can request success”, but data definition, permissions, failed retries, repeated processing, and long-term monitoring.

1. What problems do API connections usually solve

Websites can read products, submit customer leads, synchronize orders, query logistics, or trigger business processes through the interface to reduce duplicate entries.

2. First determine the person in charge of the data in the system

The product, inventory, customer and order must be clear which system shall prevail.Otherwise, the two systems cover each other, which will produce conflicts that cannot be judged.

3. The difference between active query and Webhook

Active query is suitable for timing synchronization, and Webhook is suitable for immediate notification after an event occurs.Actual projects are often used in combination, and compensation queries are set up.

4. Authentication and key management

Common methods include API Key, OAuth, and signature request.The key must be stored on the server side and the source, permission, and validity period must be restricted.

5. Failed retry and idempotent processing

The network timeout does not mean that the other party has not processed it.The interface requires a unique business number, number of retries, error queue, and manual processing entry.

6. Logs and monitoring must be able to locate the problem

At least record the request time, business number, result status and error information, but passwords, complete bank cards, or sensitive personal data should not be exposed in the logs.

7. The interface boundary should be written into the delivery scope

Third-party interface changes, call costs, current limits, test accounts, and maintenance responsibilities should be stated before production.

STEP 1Confirm data sources and fieldsConfirm the scope, person in charge and acceptance method before entering the next step.

STEP 2Design authentication and synchronization methodsConfirm the scope, person in charge and acceptance method before entering the next step.

STEP 3Handle retries, duplicates, and logsConfirm the scope, person in charge and acceptance method before entering the next step.

STEP 4Online monitoring and retention of manual entryConfirm the scope, person in charge and acceptance method before entering the next step.

Recommended Implementation Plan

A project does not need every feature on day one. It can be delivered step by step in the following order.

1Confirm data sources and fields

2Design authentication and synchronization methods

3Handle retries, duplicates, and logs

4Online monitoring and retention of manual entry
