Code
```python
from flask import Flask, request, jsonify
import RPi.GPIO as GPIO

app = Flask(__name__)

# Set up GPIO mode
GPIO.setmode(GPIO.BCM)

# Define relay pins
RELAY_PIN_1 = 23
RELAY_PIN_2 = 24

# Set up relay pins as output
GPIO.setup(RELAY_PIN_1, GPIO.OUT)
GPIO.setup(RELAY_PIN_2, GPIO.OUT)

@app.route('/lamp/on', methods=['POST'])
def turn_lamp_on():
    GPIO.output(RELAY_PIN_1, GPIO.HIGH)
    GPIO.output(RELAY_PIN_2, GPIO.HIGH)
    return jsonify({'status': 'Lamp is on'})

@app.route('/lamp/off', methods=['POST'])
def turn_lamp_off():
    GPIO.output(RELAY_PIN_1, GPIO.LOW)
    GPIO.output(RELAY_PIN_2, GPIO.LOW)
    return jsonify({'status': 'Lamp is off'})

if __name__ == '__main__':
    app.run(debug=True)
```
Note: In this example, we assume that the relay module is connected to GPIO pins 23 and 24, and the lamp is connected to the relay module. You may need to adjust the pin numbers and the relay module's configuration based on your specific setup.
