update_text_message_template

Update a text message template. (PUT /textMessageTemplates/{id}) FUB templates support %merge_field% placeholders that FUB substitutes when a human actually sends the template (not by this tool — this just saves the template text as-is). Reference: Contact: %contact_name% (full), %contact_first_name%, %contact_last_name%, %contact_email%, %contact_phone%, %contact_address%, %contact_street%, %contact_city%, %contact_state%, %contact_zipcode%, %contact_country%, %contact_rels_first_name% (first names of the contact's linked relationships, e.g. spouse/family added via peopleRelationships). Company (from Admin > Company settings): %company_name%, %company_phone%. Agent / Lender / Sender — same field set, swap the prefix (agent = assigned agent, lender = assigned lender, sender = whoever is actually sending this particular message, which may be neither): %agent_name%, %agent_first_name%, %agent_last_name%, %agent_email%, %agent_phone% (the FUB-assigned calling/texting number), %agent_mobile_phone% (their real/personal number), %agent_merge_field_1% (one free-form field each user sets in My Settings > Other Settings > Edit User Merge Field — commonly a booking link or social profile). ⚠️ %_phone% vs %mobile_phone% is genuinely ambiguous — always confirm with the user which one they mean before using either; picking wrong sends the recipient the wrong callback number. Inquiry (how the contact became a lead, e.g. clicking "Get more info" on a listing site): %inquiry_address%, %inquiry_address_url% (only if the lead source provided one), %inquiry_address_preview% (renders an HTML photo+link box — email only, meaningless in a plain-text SMS template). Recently viewed (populated only when synced with a provider that shares property views): %viewed_address%, %viewed_address_url%, %viewed_address_preview%, %last_5_preview% (up to 5 as HTML boxes, email only). Other: %source_name% (lead source, e.g. "Zillow" — "I saw your inquiry on %source_name%"), %greeting_time% ("Morning"/"Afternoon"/"Evening" based on send time — "Good %greeting_time%, %contact_first_name%"), %tour_time% (populated if the contact scheduled a tour via Zillow). Custom fields: %custom% (e.g. %custom_website%, %custom_birthday%, %custom_spouse_name%). Call list_custom_fields to confirm a field exists — but note its API name (e.g. customBirthday, camelCase) and its merge-field name (%custom_birthday%, snake_case) are different spellings of the same field, and there's no API that returns the merge-field spelling directly, so confirm the exact form with the user (or FUB's own Merge Fields dropdown in the template composer) if it's not obvious from the label. A merge field with no value for a given contact is simply left blank when the template is used — not an error, not a visible placeholder. Texting-specific, per FUB's own Compliance/Carrier Filtering guidance: initial/first-outreach text templates should include opt-out language ("Reply STOP to unsubscribe") and introduce the sender/company by name. Avoid designing a template purely for identical mass-blasting — carriers filter messages that look like spam, personalization (via merge fields) reduces that risk. If the template includes a URL, use the full URL rather than a shortened link, since shorteners are more likely to get carrier-filtered.
