Create a new contact in Propstack CRM.

Use this tool to:

• Register a new lead after a phone call

• Create a contact from a web form submission

• Add a new property owner

Auto-upserts: if a contact with the same email or old_crm_id already exists, it will be updated instead of creating a duplicate.

Use get_contact_sources first to find valid source IDs.

Create a deal linking an interested contact to a property in Propstack.

A deal represents a contact's interest in a property and tracks it through pipeline stages (e.g. Anfrage → Besichtigung → Reserviert → Notartermin → Verkauft).

Use this tool after:

• A viewing to formalize interest

• A contact inquiry about a property

• Moving a lead into the sales pipeline

Requires client_id, property_id, and deal_stage_id. Use list_pipelines or get_pipeline to find valid pipeline and stage IDs.

Link a contact as the OWNER (Eigentümer) of a property.

Use this tool to:

• Record property ownership ("Herr Müller owns Hauptstraße 12")

• Set up owner relationships for acquisition properties

• Link sellers to their properties

The ownership appears on both the contact's and the property's record.

Link a contact as a PARTNER (buyer, tenant, etc.) to a property.

Use this tool to:

• Link a buyer to a property ("Frau Schmidt is the buyer of Hauptstraße 12")

• Link a tenant to a rental property

• Create any named contact↔property relationship

The name field describes the role (e.g. "Käufer", "Mieter", "Verwalter").

Create a new property (Objekt) in Propstack CRM.

Use this tool to:

• List a new property from an acquisition call

• Create a listing from an owner inquiry

• Add a property to a project

Use get_property_statuses to look up valid status IDs. Use the relationships_attributes array to link an owner contact on creation.

rs_type values: APARTMENT, HOUSE, TRADE_SITE, GARAGE, SHORT_TERM_ACCOMODATION, OFFICE, GASTRONOMY, INDUSTRY, STORE, SPECIAL_PURPOSE, INVESTMENT.

rs_category provides sub-types (e.g. PENTHOUSE, VILLA, MAISONETTE for APARTMENT/HOUSE).

Create a search profile (Suchprofil) for a contact in Propstack.

This is THE killer feature for an AI real estate assistant. When a buyer or renter describes what they're looking for in natural language, map it to structured search criteria:

Example conversation: "Herr Weber sucht eine 3-Zimmer-Wohnung in Berlin oder Potsdam, Budget 300.000–400.000 €, muss einen Balkon haben" → client_id: <Herr Weber's ID> marketing_type: "BUY" rs_types: ["APARTMENT"] cities: ["Berlin", "Potsdam"] number_of_rooms: 3, number_of_rooms_to: 3 price: 300000, price_to: 400000 balcony: "true"

Mapping guide:

• "Wohnung" / "apartment" → rs_types: ["APARTMENT"]

• "Haus" / "house" → rs_types: ["HOUSE"]

• "kaufen" / "buy" → marketing_type: "BUY"

• "mieten" / "rent" → marketing_type: "RENT"

• "3 Zimmer" → number_of_rooms: 3, number_of_rooms_to: 3

• "3-4 Zimmer" → number_of_rooms: 3, number_of_rooms_to: 4

• "bis 400k" → price_to: 400000

• "mind. 80m²" → living_space: 80

• "mit Balkon" → balcony: "true"

• "mit Aufzug" → lift: "true"

• "mit Garten" → garden: "true"

• "mit EBK" → built_in_kitchen: "true"

• "Neubau" → construction_year: 2020

Feature booleans use strings: "true" = required, "false" = excluded, omit = don't care.

Use radius search (lat/lng/radius) for "within 5km of Alexanderplatz".

Create a new tag/label (Merkmal) in Propstack.

Tags are used to categorize contacts, properties, and activities. Optionally assign to a parent super-group (Obermerkmal) for hierarchy.

Examples: "Penthouse-Käufer", "VIP", "Kapitalanleger", "Erstbezug".

Create a task (note, to-do, appointment, or cancellation) in Propstack.

This is the central write endpoint for ALL activity types. The mode is determined by which flags you set:

MODE 1 — Note (Notiz): Just provide title + body. No special flags needed. Example: log a call note after a conversation.

MODE 2 — To-do (Aufgabe): Set is_reminder: true + due_date. Example: "remind me to call Herr Müller back tomorrow"

MODE 3 — Appointment (Termin): Set is_event: true + starts_at + ends_at. Example: "schedule a viewing at Musterstr 12 at 3pm"

MODE 4 — Cancellation (Absage): Set reservation_reason_id to a valid reason. Example: "cancel deal — buyer withdrew financing"

Always link tasks to contacts/properties/projects via the *_ids arrays so they appear in the correct activity feeds.

The body field accepts HTML content.

Create a webhook to subscribe to Propstack CRM events.

Propstack will POST a JSON payload to target_url whenever the event fires. Use HMAC verification (secret in response) to validate payloads.

Common events:

• CLIENT_CREATED — new contact added

• CLIENT_UPDATED — contact details changed

• PROPERTY_UPDATED — property details or status changed

Use this to set up automation triggers, e.g.: "Notify me when any property status changes" "Alert when a new contact is created"

Delete a contact from Propstack CRM (soft delete).

The contact is moved to a 30-day recycle bin and can be restored.

Use this tool for:

• GDPR deletion requests (Art. 17 DSGVO)

• Removing duplicate contacts

• Cleaning up test data

Delete a search profile from Propstack.

Use this tool when:

• A contact has found a property and is no longer searching

• A contact explicitly asks to stop receiving matching notifications

Delete a webhook subscription from Propstack.

Removes the webhook so Propstack will stop sending events to its URL.

Search and filter contacts in Propstack CRM.

• Search across all contact fields with 'q' parameter

The 'q' parameter searches across: first name, last name, all emails, all addresses, and all phone numbers.

Phone search ('phone_number') ignores formatting — both 015712345678 and 0157-123-456-78 will match.

Returns paginated results. Use expand=true for full details including custom fields.

Look up a contact by phone number.

This is the go-to tool for voice agent caller identification. When a call comes in, use this tool with the caller's phone number to instantly find the matching contact.

Phone matching ignores formatting — all of these find the same contact: 015712345678, 0157-123-456-78, +49 157 12345678

Use this tool to:

• Show all deals in a specific pipeline stage

A "deal" represents an interested contact linked to a property at a specific stage in a sales/rental pipeline (e.g. Anfrage → Besichtigung → Reserviert → Notartermin → Verkauft).

Use include="client,property" to get expanded contact and property details in one request.

Common queries:

• All active deals: category="qualified"

• Filter by status, type, marketing type, or project

• Find properties in a price/rent range

• List properties by size, rooms, or construction year

• Filter by custom fields with cf_ prefix parameters

The 'q' parameter searches: unit_id, street, zip code, city, district, exposé ID.

Range filter pattern: 11 numeric fields each have _from and _to variants. For example, price_from=200000 & price_to=400000 finds properties priced 200–400k. Available range fields: price, base_rent, total_rent, property_space_value, living_space, plot_area, number_of_rooms, number_of_bed_rooms, number_of_bath_rooms, floor, construction_year.

Common queries:

• "What's in Project X?": project_id=

Always returns total count. Use expand=true for custom fields.

Use this tool to:

• Send an exposé to an interested contact

• Send a follow-up email after a viewing

• Send a confirmation or rejection to a lead

Link the email to contacts, properties, and projects so it appears in the correct CRM activity feeds.

Important:

• to[] are the recipient email addresses

• cc[] are optional CC recipients

Complete lead intake workflow — dedup check, create/update contact, log notes, create deal if specific property, and set follow-up reminder.

Perfect for post-call processing from a voice agent. Handles the entire intake in one tool call:

1. If phone or email provided → search for existing contact (dedup)
