Use fields to document API parameters and responses. There are two types of fields: parameter fields and response fields.
|
|
|
|
## Parameter field
|
|
|
|
Use the `<ParamField>` component to define parameters for your APIs or SDKs. Adding a `ParamField` automatically adds an [API Playground](/api-playground/overview).
|
|
|
|
<ParamField path="param" type="string" required>
|
|
An example of a parameter field
|
|
</ParamField>
|
|
|
|
```mdx
|
|
<ParamField path="param" type="string" required>
|
|
An example of a parameter field
|
|
</ParamField>
|
|
```
|
|
|
|
### Properties
|
|
|
|
<ParamField body="query, path, body, or header" type="string">
|
|
Whether the parameter is a query, path, body, or header. Followed by the
|
|
parameter name.
|
|
</ParamField>
|
|
|
|
<ParamField body="type" type="string">
|
|
Expected type of the parameter's value.
|
|
|
|
Supports `number`, `string`, `boolean`, `object`.
|
|
|
|
Define arrays using the `[]` suffix. For example `string[]`.
|
|
|
|
</ParamField>
|
|
|
|
<ParamField body="required" type="boolean">
|
|
Indicate whether you require the parameter.
|
|
</ParamField>
|
|
|
|
<ParamField body="deprecated" type="boolean">
|
|
Indicate whether you have deprecated the parameter.
|
|
</ParamField>
|
|
|
|
<ParamField body="default" type="any">
|
|
Default value populated when the request value is empty.
|
|
</ParamField>
|
|
|
|
<ParamField body="placeholder" type="string">
|
|
Placeholder text for the input in the playground.
|
|
</ParamField>
|
|
|
|
<ParamField body="children" type="string">

|
|
</ParamField>

|
|
</ParamField>
|
|
|
|

The `<ResponseField>` component defines the return values of an API.
|
|
|
|
