Purchase mobile data

X-API-Key

POST/data/purchase

Data purchase is asynchronous. A successful accept returns HTTP 202 with status: processing. Poll GET /transactions/{id} until terminal.

Language

curl -X POST "https://api.vendpower.ng/api/v1/data/purchase" \
  -H "X-API-Key: YOUR_X_API_KEY" \
  -H "Content-Type: application/json" \
  -H "Accept: application/json" \
  -d '{
    "biller_code": "MTN",
    "plan_id": "501",
    "mobile_number": "08031234567",
    "idempotency_key": "VP_DATA_UNIQUE_001"
  }'

Authentication

Send your approved API key on every request. Keep it on your server only.

Header	Value	Required
X-API-Key	YOUR_X_API_KEY	Yes
Content-Type	application/json	Yes
Accept	application/json	Recommended

Authentication failures (401 / 403 / 429) are listed in Authentication.

Parameters

Body parameters

Name	Type	Required	Description
biller_code	string	Yes	Network code
plan_id	string	Yes	Numeric id or `api_plan_id`
mobile_number	string	Yes	11-digit Nigerian MSISDN
idempotency_key	string	Yes	Your unique purchase key (recommended `VP…`). Re-sending the same key returns `409` with the original transaction — never charges twice.
