OpenPix-Arduino-ESP32

This library is a simple and efficient library for OpenPix (https://openpix.com.br) payment. This use the REST API of OpenPix to make payments.

Installation

To install this library, you can use the Arduino Library Manager or download the library and import it to your Arduino IDE.

Usage

To use this library, you need to include it in your sketch. You can do this by adding the following line at the beginning of your sketch:

#include <OpenPix.h>

Example

Here is an example of how to use this library:

#include <ArduinoJson.h>
#include <OpenPix.h>

#define BUTTON_PIN 5

OpenPix Pix = OpenPix(OPENPIX_APPID);

void buttonsWatcher() {
  if (digitalRead(BUTTON_PIN) == LOW) {
    String pixResponse = Pix.pixCreateChargeInsecure(198); // Create a charge of R$ 1.98

    if (pixResponse == "") {
      Serial.println("Error creating charge");
      return;
    }

    JsonDocument responseDoc;
    DeserializationError error = deserializeJson(responseDoc, pixResponse);
    if (error) {
      Serial.println("Error parsing JSON");
      return;
    }

    if (responseDoc.containsKey("errors")) {
      String errorMsg = responseDoc["errors"][0]["message"].as<String>();
      Serial.println("Error: " + errorMsg);
      return;
    }

    String correlationID = responseDoc["charge"]["correlationID"].as<String>();
    // String pixQRCode = responseDoc["charge"]["pixQRCode"].as<String>();

    Serial.println("Correlation ID: " + correlationID);
    // Serial.println("Pix QR Code: " + pixQRCode);
  }
}

void setup() {
  Serial.begin(115200);
  delay(1000);
}

void loop() {
  buttonsWatcher();
}
