http_get_and_parse_json

# HTTP REST Client Get and Parse JSON example

This is an example of getting json from the internet and parsing it.

In this example, we create a wifi connection using your ssid and password (edit this in the main.c file)
and then get an https endpoint every second.

# Configure the Project

- open the project config menu (`idf.py menuconfig`)
- Configure the buffers under "HTTP REST Client"

# Build and Flash

```
idf.py -p PORT flash monitor
```
