WhatFlow vs Telnyx: Telnyx gives developers WhatsApp Business API access, including messaging, calling and template tools.

If you're a store, not a dev shop, WhatFlow is the one to install, and it's free to start.
WhatFlow vs Telnyx at a glance
- What you buy: WhatFlow is a Shopify app. Telnyx is communications infrastructure.
- Shopify: WhatFlow reads Shopify orders, adds admin extensions and plugs into Shopify Flow. On Telnyx, you build that.
- Replies: WhatFlow's team inbox has no seat fees. Telnyx doesn't ship a Shopify team inbox.
- Pricing: WhatFlow publishes plans from Free and $4.99/month. Telnyx's no-monthly-subscription statement sits under calling on its WhatsApp product page, so get messaging terms separately.
- Rating: WhatFlow's Business API app is rated 5.0 out of 5 from 55 ratings on the Shopify App Store, as of November 5, 2026.
WhatFlow isn't only for small stores. The Business API app is built on the official Meta Cloud API and is enterprise-ready: a shared inbox with assignment and filters where a 50-person team pays the same in seat fees as a team of two (nothing), native Shopify Flow triggers and actions for automation at scale, COD confirmation, catalog sharing and Shopify admin extensions. Small stores still get the easiest start there is: a Free plan with every feature.
The test template is the easy part
A developer can send a test WhatsApp template through Telnyx in an afternoon. The hard part comes after:
- Who sees the customer's reply, and where?
- How does a "Cancel" tap actually cancel the Shopify order?
- Where does your support person look up the order behind a message?
- Who fixes it when a template is rejected or a webhook breaks at 11pm on Black Friday?
In WhatFlow, those are answered: replies land in the team inbox, order replies trigger Shopify Flow, the order context sits beside the chat, and maintenance is our job. For the full build list, see app vs custom Cloud API.
How much does it cost?
WhatFlow's plans: Free (100 sends, every feature), Starter $4.99 (2,000 sends), Plus $9.99 (5,000), Growth $29 (20,000), Scale $49.99 (40,000). Say you send 12,000 WhatsApp messages a month; Growth covers it for $29, and adding staff costs nothing. Details on the pricing page.
On Telnyx, add the messaging terms you're quoted, plus developer time to build the Shopify integration and inbox, plus maintenance. Meta's per-message WhatsApp charges apply to both (Meta's pricing).
What WhatFlow includes
- Template editor with Shopify order fields.
- COD confirmation with buttons that tag or cancel orders via Flow.
- Abandoned checkout and shipping update messages.
- Native Shopify Flow triggers and actions; Shopify Sidekick can help draft the workflows.
- Live catalog sharing, saved replies, assignment and filters.
- Free theme-matched WhatsApp buttons.
An abandoned-checkout template that a WhatFlow store might run:
Hi Lucas, you left the Trail Runner 2 (size 42) in your cart. It's still there: [checkout link]. Any questions about fit? Just reply here.
What should you set up first in WhatFlow?
Don't switch everything on at once. A sensible order for a small Shopify team:
- The chat button. Free forever, theme-matched, and it starts bringing conversations in on day one.
- Saved replies. Write answers to your five most common questions (delivery time, returns, sizing, COD, order status).
- One order template. COD confirmation if you sell cash on delivery, otherwise a shipping update.
- One Shopify Flow workflow that reacts to a WhatsApp reply. The template-from-Flow guide shows the steps.
- Abandoned checkout, once you're comfortable with templates and opt-in.
Every step above is available on the Free plan.
When Telnyx might still make sense
Pick Telnyx only if you need programmable WhatsApp (or WhatsApp calling) inside your own product and have engineers who'll own it. That's real infrastructure, priced and built for that job.
The bottom line
Telnyx gives you the channel. WhatFlow gives you the whole Shopify WhatsApp workflow, from template to tagged order to answered question, with every feature on every plan and no seat fees. Install WhatFlow free and compare WhatFlow vs Bird if you're still looking at providers.
Questions worth asking
Is WhatFlow a Telnyx alternative for Shopify WhatsApp?
Yes, if you want a working app rather than an API. WhatFlow includes the Shopify integration, templates, COD confirmation, Flow triggers and a no-seat-fee team inbox. Telnyx suits teams that want programmable WhatsApp messaging or calling and will build the application themselves.
Does Telnyx charge a monthly subscription for WhatsApp?
Telnyx's WhatsApp product page places its no-monthly-subscription statement under calling, so ask for the messaging terms on their own. Either way, budget for building the Shopify integration and reply screen. WhatFlow starts free, with paid plans from $4.99/month.
Does WhatFlow charge per inbox seat?
No. WhatFlow's team inbox has no seat fees, so your support, sales and fulfilment people can all answer WhatsApp without the bill changing. You pay for a message plan, and Meta bills its WhatsApp charges separately, as it would with Telnyx.
Is the WhatFlow Free plan limited?
No features are held back. The Free plan includes templates, Shopify Flow triggers and actions, COD confirmation, catalog sharing and the team inbox. Paid plans from $4.99/month only add message allowance at lower rates, and the theme-matched WhatsApp button is free forever.
