Arkesel
Arkesel is a West African communications platform providing SMS, voice OTP, WhatsApp Business messaging, and email APIs built for the African market, with strong coverage across Ghana and Nigeria as its primary markets. Founded in Ghana, Arkesel brings deep knowledge of West African mobile network behavior, regulatory environments, and developer needs to its API platform — offering competitive African-market pricing, direct network routing for Ghanaian and Nigerian carriers, and customer support that understands the West African telecommunications context. For Nigerian developers who also serve Ghanaian users or work within West African conglomerates operating across both markets, Arkesel provides unified multi-channel communications from a single African-native platform.
SMS delivery through Arkesel reaches Nigerian mobile subscribers on MTN, Airtel, Glo, and 9mobile with sender ID support, DND compliance, and delivery reporting. The API uses a simple REST interface with API key authentication, accepting the sender, recipient, and message in a POST request and returning a message ID and status. Nigerian developers can integrate Arkesel SMS in under an hour, with documentation and code examples available in PHP, Python, JavaScript, and other common languages.
Voice OTP through Arkesel provides phone call-based verification for Nigerian users who cannot receive SMS (due to DND, no SMS coverage, or feature phone limitations). The voice OTP system calls the recipient's number and reads the OTP code using text-to-speech, providing an automatic fallback to voice when SMS OTP delivery fails or times out. Nigerian fintech apps and e-commerce platforms using Arkesel can implement SMS OTP with automatic voice retry — if the SMS is not confirmed within 60 seconds, trigger a voice call to the same number with the same code.
WhatsApp Business API through Arkesel enables Nigerian businesses to send WhatsApp template messages and engage customers in WhatsApp conversations through a managed Business API integration. Arkesel handles the Meta Business verification and WhatsApp Business API approval process on behalf of the Nigerian business, providing a more straightforward path to WhatsApp API access than going through Meta directly. Nigerian e-commerce companies, banks, and service businesses can use Arkesel WhatsApp to send order updates, payment confirmations, and customer service responses on the channel Nigerians use most.
Bulk SMS campaign management through the Arkesel dashboard allows uploading contact lists, creating message templates, scheduling sends, and monitoring delivery reports — all without writing any code. Nigerian business owners and marketing teams who are not developers can run SMS campaigns through the Arkesel web interface, while developers can automate the same campaigns through the API.
Email delivery through Arkesel supports transactional email (automated single-recipient emails triggered by application events) and bulk email campaigns, with deliverability infrastructure managed by Arkesel. Nigerian businesses wanting a single vendor for both SMS and email notifications can unify their notification infrastructure through Arkesel rather than managing separate SMS and email providers.
Arkesel pricing is designed for African market purchasing power, with NGN-compatible pricing and competitive rates for both Nigerian and Ghanaian SMS delivery. New accounts receive free trial credits for testing, and the freemium model allows Nigerian startups to build and test SMS features before committing to paid plans. Arkesel's combined SMS + WhatsApp + Voice + Email package from a single African API provider makes it a compelling choice for Nigerian developers who want to consolidate communications under a partner that understands their market.
