Frequently Asked Questions

If you have any questions, please don't hesitate to contact our support or sales team.

How does the OTPflow ensure high message delivery rates?

The Smart Multi-Channel API uses AI-powered real-time dynamic routing to optimize delivery across multiple channels, such as SMS, WhatsApp, and RCS. If a message fails or isn't delivered within the timeout window, it automatically switches to the next channel, ensuring reliable delivery and minimizing drop-offs.

Can I customize the sequence and timeout settings for message delivery?

Yes, you can define the order of channels (e.g., SMS → RCS → WhatsApp) and set timeout windows for each channel. If a message fails or no delivery report is received within the specified time, the system moves to the next channel automatically.

Are there any limitations to using the OTPflow?

Yes, the maximum combined timeout window for all channels is 5 minutes (300 seconds). Additionally, you can send between 1 to 5 messages per request. Late delivery reports may result in fallback messages being sent across multiple channels.

What are the benefits of using the OTPflow?

The API offers higher delivery rates by leveraging multiple channels, efficient resource usage by reducing redundant attempts, customizable delivery settings, cost savings through optimized retries, and real-time updates via webhooks to enhance user experience.

Is there an additional cost for using this service?

No, there are no extra charges for using the OTPflow. You are only billed for the messages sent based on the pricing of each channel activated in your account.

How does Zixflow ensure data security and privacy?

Zixflow prioritizes data security with features like end-to-end encryption, passwordless authentication, and detailed login audit logs. Hosted in world-class data centers, it ensures compliance with industry standards, keeping your business communications secure and private.
