ABS Vendor API

Sell airtime, data, electricity and airtime vouchers programmatically. One API key, three request styles, and a full sandbox so you can build and test without spending a naira.

Base URL https://absvendor.com — all endpoints are HTTPS only.

There are three ways to talk to ABS Vendor, all sharing the same API key:

NATIVE

Direct API

Richest surface — airtime, data, electricity, vouchers, meter validation. Form-encoded.

COMPATIBLE

MSorg style

JSON, drop-in for platforms built around the MaskawaSub/MSorg shape.

COMPATIBLE

Adex style

JSON, drop-in for platforms built around the Adex shape.

Authentication

Every request is authenticated with your secret API key, sent as a Bearer token in the Authorization header. Generate or rotate your key from Dashboard → API Keys.

HTTP header

Authorization: Bearer abs_live_xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

The Partner (MSorg/Adex) endpoints additionally accept Token <key> and Basic base64(username:key) for compatibility. Your key is the only credential — there is no separate partner ID.

Keep your key secret. It can spend your wallet balance. Set an IP whitelist, a daily spend cap, and (optionally) a transaction-PIN requirement on the API Keys page.

Sandbox / test mode

Add sandbox=true to any spend request (airtime, data, electricity, voucher) — or send the header X-ABS-Sandbox: 1. The request runs the full pipeline (auth, validation, ID lookup, PIN/IP/cap checks) but does not charge your wallet and does not vend. The response is shape-identical to a live one, with "sandbox": true added.

Sandbox — Direct API

curl -X POST https://absvendor.com/api/user/transaction/buy_airtime.php \
  -H "Authorization: Bearer abs_live_YOUR_KEY" \
  -F "airtimetid=MTNAIR6TFD" \
  -F "phoneno=08012345678" \
  -F "amount=100" \
  -F "sandbox=1"

Sandbox still validates. It only skips the charge + vend, so your IDs, phone format and amounts must be valid — exactly mirroring live. Read endpoints (balance, networks, plans, system data, validate meter) behave the same in either mode.

Rate limits & controls

Rate limit: 300 requests per 60 minutes per key.
IP whitelist (Partner endpoints): if set, requests from other IPs are rejected (403).
Daily spend cap (Partner endpoints): caps NGN spent per UTC day (429 when exceeded).
Transaction PIN (Partner endpoints): if enabled, send pin on every spend call.

Responses & errors

Each style uses its own envelope. A successful spend always means the wallet was debited and the order was created.

Direct API envelope

Success / failure

// success
{ "status": true, "text": "Successful", "data": { ... } }

// failure
{ "status": false, "text": "Please check your input...",
  "error": { "code": 141, "text": "The body request is not valid..." } }

Partner MSorg envelope

Success / failure

{ "Status": "successful", ... }
{ "Status": "failed", "message": "<reason>" }

Partner Adex envelope

Success / failure

{ "status": "success", ... }
{ "status": "failed", "message": "<reason>" }

HTTP	Meaning
200	Success
400 / code 141	Invalid or missing parameter (often a wrong product ID — see below)
401	Missing/invalid API key, or PIN required and wrong/absent
403	API disabled for key, or IP not whitelisted
404	Unknown network / plan / provider
429	Rate limit or daily spend cap exceeded

Finding product IDs

This is the #1 cause of code 141. Airtime and data use different product IDs, and the network name (e.g. "MTN") is never a valid ID. Always pull live values from Get System Data (Direct) or List Networks / List Data Plans (Partner).

You're buying	Send as	Where to get it	Example
Airtime	`airtimetid`	System Data → `airtimeproviders[].product_trackid` (or `.trackid`)	`MTNAIR6TFD`
Data	`airtimetid` = network, `cardunittid` = plan	List Data Plans → `network_id` + `id`	`MTN56TFD` + `6BO1H`
Electricity	`provider_tid`	System Data → electricity services	disco service trackid
Voucher	`airtimetid` = network, `cardunittid` = unit	System Data → `voucherproviders[]`	`MTNAIR6TFD` + `HBSI2`

Common gotcha: MTN56TFD is the MTN data network. For airtime use the MTN airtime ID (MTNAIR6TFD or its provider trackid). Mixing them returns code 141.

Tip: The Direct API does not enforce the per-key IP/cap/PIN controls — those apply to the Partner endpoints. If you rely on those guardrails, integrate against the Partner API.
