Arduino en ESP32

Code example

There is no SDK for Arduino en ESP32 and none is needed: one HTTP request with a key in the header, a template name and your fields. The example below is the whole integration.

How to set it up

  1. 01Create a key in the dashboard under Keys and keep it out of your source.
  2. 02Send the request below; the answer holds the job id and its status.
  3. 03Want to know the paper moved? Poll /v1/jobs/{id}, or take an outgoing webhook.

The request

HTTPClient http;
http.begin("https://instntprint.com/v1/jobs");
http.addHeader("Content-Type", "application/json");
http.addHeader("Authorization", String("Bearer ") + SLEUTEL);
http.POST("{\"printer\":\"Balie\",\"template\":\"Kassabon\",\"data\":{\"totaal\":\"3.80\",\"betaalwijze\":\"Pin\"}}");
http.end();
