I got the following curl example to connect to an API:
curl -H "Accept: application/vnd.conekta-v0.2.0+json" \
-H "Content-type: application/json" \
-u 1tv5yJp3xnVZ7eK67m4h: \
-X POST -d '{
"currency":"MXN",
"amount": 20000,
"description":"Stogies",
"reference_id":"9839-wolf_pack",
"cash": {
"type":"oxxo"
},
"details": {
"name":"Wolverine",
"email":"a href="mailto:logan@x-men.org" rel="nofollow"logan@x-men.org/a",
"phone":"403-342-0642"
}
}' https://api.conekta.io/charges
but it confuses me about how to put the " -u 1tv5yJp3xnVZ7eK67m4h"
please help me
