Unlimited messages without banning

The official API allows a high volume of messages within Meta's policies without the risk of blocking.

Webhooks and native integrations

Connect existing systems like ERP, CRM, and e-commerce via documented RESTful API.

Multi-number and multi-agent

Official WhatsApp API

Direct connection to Meta's official API, ensuring stability, speed, and compliance with policies.

Green verification badge

Assisted process for obtaining the verified badge that increases trust and message open rates.

Account verification and official seal

Nexloo handles the business verification with Meta and the request for the badge. The client sees the company's name instead of a random number — and decides in seconds whether to respond.

No limit on connected devices

How many agents do you need at the same number, without a phone on the desk and without the instability of keeping a device connected all day long.

Approval of models accompanied

You write the model, the platform sends it to Meta, and shows the status. Rejections come with a reason, and adjustments are made before the campaign relies on them.

24-hour window controlled

Within the window, the conversation is free and without model costs; outside of it, only approved templates are sent. The platform shows the status of each conversation.

Delivery and read receipt

Sent, delivered, and read come as the status of each message. For billing and mandatory communication, this record is the difference between notifying and proving that you notified.

Click-to-WhatsApp ads

Meta campaigns that open a conversation go directly to the official number, with the source campaign tagged in the contact — and attribution stops being a guess.

Quality monitor of the number

Meta maintains a quality indicator on your number and limits sending when it drops. The platform monitors this indicator and alerts before the limitation.

Sending tier escalation

The daily conversation limit increases according to the number's history. The platform shows what step you are on and what is needed for the next one.

Migration of the number you already use

The current number can be migrated to the API while keeping customer contacts. There's no need to share a new number or restart the database.
