Solution to 429 errors in mercadoago test API

mp.py

# tldr: Retry the request until you got a non-error response.
#       In my own experience, in less than 40 attempts you can get a non-error response.

# For the customer API (Python):

response = api_call(...)['response']
response_status = response.get('status')
attempts = 0
while response_status == 429 and attempts < max_attempts:
    response = api_call(...)['response']
    response_status = response.get('status')
    attempts += 1
    
# For the cards API (Python):

response = api_call(...)['response']
response_status = response.get('status')
attempts = 0
while response_status in (404, 500) and attempts < max_attempts:
    response = api_call(...)['response']
    response_status = response.get('status')
    attempts += 1
    
# For the payments API (Python):

response = api_call(...).get('response', {})
response_status = response.get('status')
attempts = 0
while response_status in (400, 500) and attempts < max_attempts:
    response = api_call(...).get('response', {})
    response_status = response.get('status')
    attempts += 1
