If you run a wholesaling or investor-lead pipeline through Follow Up Boss, you already know the CRM's built-in texting was not built for your outbound. It works fine for a buyer's agent replying to an inbound lead. It works badly for a shop that pulls skip-traced homeowner lists and needs to reach hundreds of them a day. This is about the gap between those two use cases, and how to route SMS out of Follow Up Boss through a channel that does not sit behind the same wall.
Why Follow Up Boss's Native Texting Wasn't Built for This
Follow Up Boss calls it "Business Registration," but it is the same thing every other platform calls it: A2P 10DLC, the carrier-mandated vetting regime for application-to-person text traffic sent from standard 10-digit numbers. Follow Up Boss's own help center is direct about it: you have to register your business information before carriers will reliably deliver texts sent from the platform, and unregistered numbers get filtered.
That registration step is not the real problem for a wholesaler. The real problem is what Follow Up Boss's own compliance guidance says once you're registered: do not cold-text or cold-call leads from Follow Up Boss. That instruction is not a suggestion buried in a blog post, it is the platform's stated policy for the number it issues you. A wholesaling operation whose entire acquisition engine is outbound to homeowners who have never contacted you first is, by definition, running the exact workflow the platform tells you not to run on it.
Even when the underlying activity is legitimate, register the campaign as "real estate" and the throughput still suffers. Real estate wholesaling campaigns routinely get approved by carriers and then filtered to under 20% delivery on the actual send, with no bounce message telling you which texts landed. You pay for registration and still don't know if the homeowner ever saw your text.
What Changes When You Route Around A2P
Android Texter sends SMS from a real, user-owned Android handset rather than through a carrier-registered business number. A message sent that way looks exactly like any other text you'd send a friend: person-to-person (P2P), not application-to-person. A2P 10DLC's registration, campaign approval, and content filtering apply to the A2P path. They do not apply to a message that originates from a phone's own SMS stack.
That is an architecture difference, not a compliance shortcut. The Telephone Consumer Protection Act still governs who you can text and what you can say to them, regardless of which pipe the message travels through. The FCC's TCPA rules require prior express consent for non-emergency marketing texts to a wireless number, and that obligation sits on the operator, not the sending platform. Nothing about swapping Follow Up Boss's native texting for an Android Texter connection changes who you're allowed to contact or what consent you need to have on file. It changes whether the carrier throttles your delivery before the TCPA question ever comes up.
The Bridge: Follow Up Boss Webhooks to Android Texter's API
The two systems don't talk to each other out of the box, but both expose exactly what you need to wire them together.
On the Follow Up Boss side, go to Admin > API to get your API key, then register a webhook by sending a POST to https://api.followupboss.com/v1/webhooks with the event you want to listen for and the URL you want it delivered to. Authentication is HTTP Basic Auth: your API key as the username, password left blank. Requests to the webhooks endpoint also require an X-System header identifying your integration. Useful trigger events include peopleTagsCreated (fires when you tag a contact) and peopleStageUpdated (fires on a pipeline stage change). Follow Up Boss caps you at two registered webhooks per event type, and your receiving endpoint has to return a 2XX response within 10 seconds or the delivery is treated as failed.
The webhook payload gives you the event type and the person's ID, not their phone number, so your relay needs a second call: a GET to https://api.followupboss.com/v1/people/{id} (same Basic Auth) to pull the contact's name and phone number before you can send anything.
On the Android Texter side, generate an API key at /dashboard/settings/api-keys (keys are prefixed atx_) and send it as the X-API-Key header. A POST to /api/v1/messages/send queues the outbound text through your paired Android device; the full request and response shapes are documented at /api/openapi.json and browsable in the interactive Swagger UI at /api/swagger. Sends are rate-limited to 10 requests per second with a burst of 20, which is more headroom than a single relay function will ever need.
The relay itself is a small piece of glue: receive the Follow Up Boss webhook, look up the contact, call the Android Texter send endpoint. You can write it as a short serverless function, or build it no-code with a tool like Zapier's or Make's generic webhook catch-and-post actions, since both legs are plain HTTPS calls with a JSON body. Test it against one tagged contact before pointing it at your whole pipeline.
If you want replies to show up somewhere your team already looks, Android Texter's own webhook system can close the loop the other direction: registering for the message.received event at /api/v1/webhooks lets you post inbound replies wherever you need them, including back into a Follow Up Boss note via a second API call, so a reply doesn't just live in the Android Texter inbox and nowhere else.
Pick a Trigger That Matches Your Consent, Not Your Import
The trigger you wire this to matters more than the code. peopleCreated firing the instant a scraped list gets imported is the same cold-blast pattern that gets a number burned, whether you're sending through Follow Up Boss or anywhere else. A tag-based trigger that a person applies after confirming a legitimate contact basis, DNC scrub done, prior relationship or opt-in documented, is a materially different workflow and a materially different risk profile.
If you're running real volume, spread it across paired devices instead of one number. Android Texter supports pairing multiple Android phones to a single account and targeting a specific device_id on each send, or letting it auto-route to the first device online. Wholesalers running outbound at scale generally keep each line to roughly 100 to 200 sends a day, split across three to five devices, rather than pushing thousands through one number and tripping a carrier's velocity filter.
What This Doesn't Solve
Swapping the sending channel doesn't touch your compliance obligations. You still need to scrub against the National DNC registry before any send, document consent or an established relationship for every contact you text, and honor STOP, UNSUBSCRIBE, CANCEL, END, and QUIT the same way you would on any other line. None of that gets easier or harder because the message routed through a phone instead of a registered campaign. Android Texter doesn't reduce TCPA exposure and doesn't review your lists or your copy for you; it removes the carrier-side registration and filtering layer that sits on top of the TCPA, not the TCPA itself.
Frequently Asked Questions
Does this replace Follow Up Boss's texting feature entirely?
Not necessarily. Many teams keep native Follow Up Boss texting for warm, inbound-originated conversations where the registered number's throughput is fine, and route the higher-volume, list-driven outbound through Android Texter instead. You can run both at once.
Do I still need Follow Up Boss's Business Registration if I switch outbound to Android Texter?
If you keep using Follow Up Boss's native texting for any contacts, yes, that registration requirement doesn't go away for that channel. It just stops being the only path your outbound has to travel through.
Will replies land back in Follow Up Boss automatically?
Not without building the return leg. Replies to an Android Texter number arrive in Android Texter's own inbox. If you want them logged on the Follow Up Boss contact record, you point Android Texter's message.received webhook at a small handler that writes a note back through the Follow Up Boss API.
Does routing around A2P 10DLC lower my TCPA risk?
No. A2P 10DLC and the TCPA are separate things enforced by different parties, a carrier consortium and the FCC/courts respectively. Changing the carrier-side path changes nothing about who you need consent to text or how you have to handle opt-outs.
What's the fastest way to test this without writing code?
Use a no-code webhook tool as the relay: catch the Follow Up Boss webhook, add a step to call the Follow Up Boss people endpoint for the phone number, then add a step to call Android Texter's send endpoint. You can have a working test in under an hour before deciding whether to formalize it into a standalone function.
If your outbound is bottlenecked by a carrier-registered number that filters half your sends before a homeowner ever sees them, Android Texter gives that traffic a real phone to send from instead. Pair a device, generate an API key, and wire it to the Follow Up Boss trigger that actually reflects your consent basis, not your import job.
