Examples

Use POSTMAN to Write Channel Settings

You can use POSTMAN to try out your HTTP requests using the RESTful API for ThingSpeak. This example shows how to write new channel settings using POSTMAN.

Using an existing channel, change the channel name to Updated Channel and the field 1 title to Heart Rate. Also change the sharing to Public.

PUT https://api.thingspeak.com/channels/CHANNEL_ID
    api_key=XXXXXXXXXXXXXXXX
    name=Updated Channel
    public_flag=true
    field1=Heart Rate

1. In POSTMAN, select PUT from the drop-down list of HTTP verbs and enter api.thingspeak.com/channels/<CHANNEL_ID>.json in the address bar, replacing <CHANNEL_ID> with the channel of interest.

2. Enter the parameter api_key in the value column, enter your User API Key, which is found in Account > My Profile.

3. Enter additional parameters and values:

   • name, Value: Updated Channel

   • field1, Value: Heart Rate

   • public_flag, Value: True

The response is in JSON format. Note the server response value of 200 OK, indicating successful writing of new channel settings.

The new channel settings are now available on your channels page.
