What does the product manager need to know about the api interface

1. As a product manager, you need to understand the following aspects of the API interface:

1. Function: The function of the API interface refers to the business functions it provides, including data query, modification, addition, deletion, calculation, etc., and which API interfaces need to be called are determined according to the needs of the product.
2. Request method and parameter passing: API interface request methods include GET, POST, PUT, DELETE, etc., and select the corresponding request method according to the functional requirements. Parameter passing refers to the parameters that need to be passed when using the API interface, including required parameters, optional parameters, etc.
3. Interface documentation: Interface documentation is an important way for product managers to understand the API. The documentation should include basic information about the interface, request parameters, response format, error codes, etc.
4. Interface permissions: Interface permissions refer to the restrictions on access to the interface, including whether an account and password or API key is required to access the interface, and the permission level for accessing the API interface.
5. Interface security: Interface security includes measures such as data security for interface transmission, user authentication, and security code protection.
6. Interface performance: Interface performance includes interface response time, concurrency and other indicators, and make corresponding design plans according to product requirements. At the same time, it is also necessary to pay attention to the stability of the interface to ensure the stability and reliability of the interface operation.
7. Interface integration: Interface integration refers to the integration of multiple API interfaces to form a complete business process, including data transmission, data synchronization, data conversion, etc.
8. Interface log: The interface log records important information such as interface access, response time, error information, etc., which is very helpful for monitoring the operation of the interface and troubleshooting.

The above are some important aspects of the API interface that product managers need to understand. While understanding these aspects, the product manager also needs to master certain technical knowledge and understand the working principle of the API interface, so as to better coordinate the work of development, testing, operation and maintenance departments, and ensure the efficient, stable and safe operation of the API interface .

2. As a product manager, I can introduce the operation process of the API interface to customers. The specific steps are as follows:

1. Determining requirements: First, it is necessary to clarify which business functions need to be implemented by calling the API interface, and specify the usage scenarios of the API interface.
2. Find the API interface: After determining the requirements, you need to find the appropriate API interface. You can find the appropriate API interface through search engines, developer communities, API platforms, and other channels.
3. ​​​Register API interface ​​: After finding a suitable API interface, you need to register an account on the corresponding platform and obtain an API key to obtain access to the API interface.
4. Test interface: After obtaining the key of the API interface, you can use tools such as POSTMAN to test the API interface to ensure that the API can run normally and return correct results.
5. Development documents: After the API interface can be accessed normally and returns results, you need to check the API-related development documents to clarify the parameter transfer form, data format and other related information required by the API.
6. Call API: According to the requirements defined in the API interface document, pass the parameters to be passed into the API interface, call the API interface, and get the returned result.
7. Processing the returned result: After obtaining the returned result of the API interface, it needs to be parsed and processed accordingly, for example, displayed on the page or stored in the database.
8. Monitoring the API interface: When using the API interface, it is necessary to monitor the access status and response time of the API interface from time to time, and deal with various problems in a timely manner.

The above is the operation process of the API interface. Through this series of steps, the seamless call to the API interface can be realized, and the overall efficiency and user experience of the product can be improved.
