ghl-models

Rust data models (DTOs) for the GoHighLevel (HighLevel) API, generated from HighLevel's official OpenAPI specifications.

2,417 structs covering both API versions — v2 (2,417 total: 1,074 V2 + 1,329 V3 structs and 14 documented string-enum aliases) across 45 API modules, from contacts and invoices to ad-publishing, social-planner, voice-ai, and saas.

Usage

Every module is behind a cargo feature, because enabling everything means thousands of structs. Pick what you need:

[dependencies]
ghl-models = { version = "0.3", features = ["invoices", "payments"] }

use ghl_models::v2::invoices::{CreateInvoiceDto, InvoiceItemDto};

let invoice = CreateInvoiceDto {
    alt_id: location_id,
    alt_type: "location".into(),
    name: "August retainer".into(),
    currency: "USD".into(),
    items: vec![/* InvoiceItemDto { .. } */],
    ..Default::default()
};

Feature-gating matters: one module compiles in ~1.3s, all 45 take ~30s.

Use features = ["full"] to get everything (mostly useful for exploring in docs.rs).

API versions

V3 renames three modules (ad-manager→ad-publishing, social-media-posting→social-planner, saas-api→saas), adds chat-widget, and switches some paths from camelCase to kebab-case (/campaigns/removeAll → /campaigns/remove-all). Both live side by side: ghl_models::v2::* and ghl_models::v3::*.

How these types are generated

• Fields the spec marks required are non-Option; the rest are Option<T> that skip serialization when None, so partial updates work naturally.
• Arrays are Vec<T> with #[serde(default)] — an absent list reads as empty.
• String enums are String, with allowed values in the doc comment. GoHighLevel adds enum values without notice, and a closed Rust enum would turn that into a deserialization failure.
• Anonymous nested objects and multi-branch compositions (oneOf/anyOf) become serde_json::Value; a single-$ref allOf wrapper resolves to the referenced type.
• Unknown response fields are ignored, never rejected, so upstream additions can't break your build.
