Understanding Reloadly's Airtime API
Reloadly built one of the most comprehensive mobile top-up APIs available to B2B businesses. Launched in 2018, the Miami-based company has grown to cover 150+ countries and 700+ mobile network operators — a catalog that spans the major airtime remittance corridors from North America and Europe into Africa, South Asia, the Caribbean, and Latin America.
The underlying model is classic aggregation: Reloadly negotiates relationships with mobile operators and exposes them through a unified REST API. For businesses building products on top of the airtime market — diaspora apps, fintech platforms, telecom resellers — this means a single integration replaces what would otherwise be dozens of bilateral operator agreements.
Understanding how to access this API, and what the access pathway looks like for different business types, is the practical starting point for any reseller evaluating Reloadly.
What the Airtime API Covers
Mobile Airtime Top-Ups
The core product: sending prepaid credit to a mobile number. A customer in London initiates a transfer; within seconds, their family member's phone in Lagos, Dhaka, or Manila receives airtime credit. Reloadly handles the operator routing, the foreign exchange (where applicable), and the delivery confirmation.
The API returns a transaction ID, delivery status, and operator-specific metadata. For consumer-facing apps, this data feeds real-time confirmation screens. For B2B platforms running at volume, it feeds reconciliation and reporting systems.
Data Bundles
Many operators sell data as a separate SKU rather than bundled with airtime. Reloadly's API includes data bundle products where operators support them, allowing resellers to offer data-specific top-ups alongside voice credit.
Availability varies by operator. Some carriers list both; others only one. The API's operator discovery endpoint includes product-level metadata so resellers can dynamically surface what is available per operator rather than hardcoding product lists.
International Top-Ups
International top-up is the dominant use case for diaspora and remittance platforms. The sender (typically in a high-income country) credits airtime to a recipient's SIM in a low-income country. Reloadly is particularly well-suited here because its coverage depth in recipient markets — Nigeria, Ghana, India, Bangladesh, Philippines, Mexico, Colombia — is strong.
The exchange rate mechanics are handled by Reloadly. The reseller charges the sender in a source currency; the operator credits the recipient in local denomination. Reloadly manages the currency conversion, though resellers need to understand their margin structure across currency pairs.
Who Uses Reloadly's API?
Diaspora Money Transfer Apps
The largest single use case for Reloadly's international top-up coverage. Money transfer operators have historically focused on bank transfers and cash pickup as their core product. Mobile airtime top-up is now a standard add-on — users already trust the platform for sending money, and extending that to phone credit requires minimal user education.
For these platforms, coverage breadth is paramount. A diaspora app serving African communities in the UK needs Nigeria, Ghana, Senegal, Côte d'Ivoire, and a dozen other countries to be reliable. Reloadly's West African operator relationships are specifically noted in the market as strong.
Fintech Platforms and Digital Wallets
Digital wallets and payment apps are expanding their utility offerings. Airtime top-up is a low-friction feature that drives weekly active usage — users who might not transfer money every week will frequently top up their own or a family member's phone.
For these platforms, Reloadly's API integration is relatively lightweight: the heavy lifting of operator relationships, currency conversion, and delivery routing is done. The platform adds it as a feature rather than building a telecom business from scratch.
Telecom Resellers and MVNOs
Traditional telecom resellers that have historically operated through carrier-specific portals or EDI feeds are increasingly moving toward API-first architectures. Reloadly offers these businesses a way to unify their operator portfolio under a single interface and expand their coverage without new carrier contracts.
B2B Marketplaces and Aggregation Platforms
Companies building wholesale platforms — like FoxReload itself — use Reloadly as one supplier in a multi-supplier stack. The API's quality and coverage make it a default choice for airtime in the supplier mix.
Direct Reloadly Access: What It Requires
Getting direct B2B access to Reloadly is not instant. The platform operates a managed onboarding process:
Application and review. New business accounts require an application that includes business details, use case description, and projected volumes. Reloadly reviews applications before granting API access.
Contract and terms. Commercial access involves a contract covering pricing, payment terms, acceptable use, and compliance requirements (particularly around KYC/AML given the nature of airtime transactions in some jurisdictions).
Volume commitments. Competitive pricing on direct accounts typically requires minimum monthly volume commitments. Businesses processing high volume can negotiate favorable margins; startups and lower-volume operators may find the terms less attractive.
Technical onboarding. After commercial approval, technical onboarding provides API credentials, sandbox access, and documentation. This part is generally smooth given Reloadly's developer-first design.
For established businesses with clear volume and a defined use case, this process is manageable. For startups or businesses that need immediate market access without committing to volume floors, the friction is significant.
FoxReload: Immediate API Access to Reloadly's Catalog
FoxReload is a wholesale B2B platform that aggregates Reloadly alongside 12 other suppliers — Zendit, Xsolla, Tillo, Blackhawk, and others — under a single API. For resellers evaluating Reloadly, FoxReload offers a materially different access path.
No Direct Contract Required
FoxReload holds the supplier relationships. Resellers onboard to FoxReload once and gain access to Reloadly's airtime and data bundle catalog without a separate Reloadly application or contract. This is meaningful for businesses at the early stage or those that need to move quickly.
Automatic Supplier Routing
When a top-up request comes in for a specific country and operator, FoxReload routes the transaction to the optimal supplier based on availability, pricing, and success rates. For a given operator, the best supplier may be Reloadly; for another, it may be Zendit or a different supplier with stronger coverage.
This routing means resellers effectively get better-than-single-supplier performance without managing multiple supplier relationships themselves. Fill rates improve because if one supplier has a delivery issue, another routes the transaction.
Broader Product Portfolio
Through FoxReload, resellers access not just Reloadly's airtime catalog but also gift cards from Tillo and Blackhawk, gaming content from Xsolla, and other product types from the full 13-supplier network. Building a multi-category digital top-up business becomes a single-integration project rather than a multi-supplier negotiation exercise.
Step-by-Step: Accessing Reloadly Through FoxReload
Step 1: Create a FoxReload account. Register at foxreload.com and complete the B2B onboarding process. No minimum volume is required to start.
Step 2: Get API credentials. Upon approval, receive your API key and access credentials. A sandbox environment is available for pre-production integration and testing.
Step 3: Browse the catalog. Query the operator catalog endpoints to identify Reloadly and other suppliers available in your target countries. The API returns operator-level metadata including product types, denominations, and delivery characteristics.
Step 4: Go live. Complete sandbox testing, switch to production credentials, fund your account, and begin processing transactions. FoxReload handles supplier routing automatically.
Technical Considerations for Integration
When building an airtime top-up product on top of Reloadly's catalog — whether via direct access or FoxReload — several technical decisions matter:
Denomination handling. Some operators use fixed denominations (specific credit amounts); others use range-based pricing (any amount within min/max). The API distinguishes these, and product UIs need to handle both patterns.
Operator discovery. Rather than hardcoding operator lists, build catalog lookups dynamically. Operators are added, removed, or modified. Dynamic lookups ensure your product surface stays current without manual catalog maintenance.
Error handling. Airtime transactions can fail for various reasons: invalid number, operator issue, insufficient balance, network timeout. Robust error handling with clear user messaging is essential for consumer-facing products.
Webhook integration. For asynchronous delivery scenarios, webhook callbacks provide definitive delivery confirmation. Building webhook handling into the integration from the start prevents gaps in transaction reconciliation.
Conclusion
Reloadly's airtime API remains the strongest single-supplier option for businesses that need wide geographic coverage for mobile top-ups. The platform's 150+ country, 700+ operator catalog, REST API with OAuth2, and real-time delivery make it the default evaluation choice for diaspora platforms, fintech apps, and international telecom resellers.
The access question — direct vs. FoxReload — depends on business stage and requirements. Direct access gives full control but requires application, approval, and volume commitments. FoxReload provides immediate access to Reloadly's catalog alongside 12 other suppliers, without a separate contract, and with automatic routing that improves fill rates across the supplier mix.
