ghl-models

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

2,417 types across 45 API modules and both API versions — 1,074 structs for v2, 1,329 for v3, plus 14 documented string-enum aliases. Everything 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 = "0.5", 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

	Modules	Operations	Structs
`v2` — current stable (`Version: 2021-07-28`)	41	576	1,074
`v3` — newer (`Version: v3`)	42	627	1,329

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.

Regenerate after HighLevel updates its specs:

python3 xtask/generate_models.py /path/to/highlevel-api-docs crates/ghl-models

Full reference

Every model, field, and enum value is documented per module in the API reference, and field-by-field on docs.rs. Large repeated value lists (country codes, timezones) live in shared enums.
