# Withings API
## Token expiry
When the access token expires, HTTP status `200 OK` is returned, but the response body is as follows:
```json
{
"status": 401,
"body": {},
"error": "XRequestID: Not provided invalid_token: The access token provided is invalid"
}
```
## Fetching health data
Health records can be fetched via GET request as follows:
```http
https://wbsapi.withings.net/measure?action=getmeas&meastypes=9,10,54,71,11
```
The type of vitals measurement is mapped as follows:
| Code | Type | Unit |
|------|--------------------------|------|
| 9 | Diastolic Blood Pressure | mmHg |
| 10 | Systolic Blood Pressure | mmHg |
| 11 | Heart Rate | bpm |
| 54 | SP02 | % |
| 71 | Body Temperature | °C |
Note the `unit`-field in the response.
For body temperature, the `unit`-field has the value `-3`.
This means that to get the body temperature in °C, you must multiply the `value` by `10^(-3)`.
The time of measurement can be parsed from the `measuregrps`'s `date` field.
A successful response looks like so:
