## List ProjectSharingClientRelations

`GET /entities/ProjectSharingClientRelations`

Returns the ProjectSharingClientRelations the API application can read, one page at a time. In the list envelope, `total` counts every match and `page_info` pages through them.

| Parameter | In | Type | Description |
| --- | --- | --- | --- |
| `include-deleted` | query | boolean | Include soft-deleted records. Lists only; get-by-id refuses it. |
| `first` | query | integer | Page size. Default 30, maximum 100; a larger value is refused with HTTP 400, code 117. (default 30, 1 to 100) |
| `last` | query | integer | Return the last N records of the result; together with `first`, the last N of the first M. Maximum 100. (1 to 100) |
| `before` | query | string | Cursor from `page_info.start_cursor`, to page backwards. URL-encode it. |
| `after` | query | string | Cursor from `page_info.end_cursor` of the previous page. URL-encode it: cursors are base64, and a raw + becomes a space. |
| `expand` | query | string | Related records to return inline instead of their URIs, comma-separated; dots reach nested relations, as in `account_relations.account`. |
| `order-by` | query | string | Fields to sort by, comma-separated. A leading - sorts descending, as in `-modified`; dotted paths sort by related fields. |
| `filter` | query | object | `filter[field]=value`. Separate several values with a raw comma (OR), as in `filter[name]=north,south`. Encode a comma that belongs to a value as %2C. URLSearchParams and Python requests encode every comma, so build the filter part of the query string yourself. Dotted paths filter on related records, as in `filter[owner.email]`. Encode a + in a value as %2B: query values are form-decoded, so a raw + becomes a space. |
| `filter-op` | query | object | `filter-op[field]=operator`, one per field: eq (the default), ieq, not-eq, not-ieq, contains, icontains, starts, istarts, ends, iends, gt, gte, lt, lte, between, null, not-null, empty and not-empty. null, not-null, empty and not-empty take no filter value; gt, gte, lt and lte take exactly one. |
| `load-only` | query | string | Fields to return, comma-separated (raw or encoded commas both work here); dots select nested fields, as in `owner.id`. All fields are returned without it. Lists only: get-by-id refuses it with HTTP 400, code 118. |

Responses: 200 (Page of ProjectSharingClientRelation records.: `success`, `total`, `page_info`, `data`), 400, 401, 429, 500.

```bash
curl 'https://{region}.api.coevera.com/api/v100/rest/spaces/{space_id}/entities/ProjectSharingClientRelations?first=10' \
  --user "$COEVERA_API_KEY:$COEVERA_API_SECRET"
```

## Create ProjectSharingClientRelation

`POST /entities/ProjectSharingClientRelations`

Creates one record and answers 201 with it.

| Parameter | In | Type | Description |
| --- | --- | --- | --- |
| `validation-level` | query | integer | Bit mask that relaxes validation on this write. 0 (the default) validates everything. Bits: 2 skip unchanged fields, 4 skip admin-defined validations, 8 allow read-only fields, 16 skip relation checks, 32 skip value checks, 64 skip invalid recalculations, 128 skip step-checklist gates, 256 add conditional field requirements, 512 skip uniqueness checks. Add bits together (20 = 4 + 16); member names and comma lists such as 4,16 work too. A value with an internal-only bit is refused with HTTP 400, code 117. |

Request body: The new record's fields. Relations are set by id. Schema `createProjectSharingClientRelationInput`. Required: `client_id`, `project_id`.

Responses: 201 (The created ProjectSharingClientRelation record.: `success`, `data`), 400, 401, 422, 429, 500.

```bash
curl 'https://{region}.api.coevera.com/api/v100/rest/spaces/{space_id}/entities/ProjectSharingClientRelations' \

  "project_id": "d7000000-0000-4000-a000-000000000001"
}'
```

## Get ProjectSharingClientRelation

`GET /entities/ProjectSharingClientRelations/{id}`

Returns one record by id. `expand` returns related records inline instead of their URIs.

| Parameter | In | Type | Description |
| --- | --- | --- | --- |
| `id` | path | string (uuid) | Required. Id of the ProjectSharingClientRelation record to retrieve. |
| `expand` | query | string | Related records to return inline instead of their URIs, comma-separated; dots reach nested relations. The only parameter this call accepts. |

Responses: 200 (The ProjectSharingClientRelation record.: `success`, `data`), 400, 401, 404, 429, 500.

```bash
curl 'https://{region}.api.coevera.com/api/v100/rest/spaces/{space_id}/entities/ProjectSharingClientRelations/de000000-0000-4000-a000-000000000001' \
  --user "$COEVERA_API_KEY:$COEVERA_API_SECRET"
```

## Update ProjectSharingClientRelation

`PATCH /entities/ProjectSharingClientRelations/{id}`

Changes the fields you send and leaves the rest as they are; there is no PUT.

| Parameter | In | Type | Description |
| --- | --- | --- | --- |
| `id` | path | string (uuid) | Required. Id of the ProjectSharingClientRelation record to update. |
| `validation-level` | query | integer | Bit mask that relaxes validation on this write. 0 (the default) validates everything.

Add bits together (20 = 4 + 16); member names and comma lists such as 4,16 work too. A value with an internal-only bit is refused with HTTP 400, code 117. |

Request body: The fields to change. Schema `updateProjectSharingClientRelationInput`.

Responses: 200 (The changed ProjectSharingClientRelation record.: `success`, `data`), 400, 401, 404, 422, 429, 500.

```

## Create or update ProjectSharingClientRelations in a batch

`POST /entities/ProjectSharingClientRelations/batch-modify`

An item with an `id` updates that record; an item without one creates a record. By default one invalid item fails the whole call with HTTP 422 and nothing is written; with `rollback-method=1` the response has an id or an error for each item, in input order.

| Parameter | In | Type | Description |
| --- | --- | --- | --- |
| `validation-level` | query | integer | Bit mask that relaxes validation on this write. 0 (the default) validates everything. Bits: 2 skip unchanged fields, 4 skip admin-defined validations, 8 allow read-only fields, 16 skip relation checks, 32 skip value checks, 64 skip invalid recalculations, 128 skip step-checklist gates, 256 add conditional field requirements, 512 skip uniqueness checks. Add bits together (20 = 4 + 16); member names and comma lists such as 4,16 work too. A value with an internal-only bit is refused with HTTP 400, code 117. |
| `rollback-method` | query | integer | 0, the default: one failed item fails the whole batch (HTTP 422, or 404 for an unknown id) and nothing is written. 1: the valid items are written and the call answers 200 with success false and one result per item, an id or an error, in input order. Check every item. (default 0) |

Request body: A JSON array of records: an item with an `id` updates, an item without one creates. Schema `batchProjectSharingClientRelationInput`. Required: `client_id`, `project_id`.

Responses: 200 (Result per item, in request order: the id of the created or updated record, or the error.: `success`, `data`), 400, 401, 422, 429, 500.

## Errors

Every error body has `success: false`, `http_status`, `code`, `name` and `message`. Branch on `code`: the status alone does not tell a missing permission from a bad parameter.

| HTTP | When |
| --- | --- |
| 400 | Bad request: a bad or unknown parameter (codes 117, 118), a missing permission (code 50), conflicting data (code 2002) or any other API error. The REST API answers 400 where others answer 403 or 409; check `code`. |
| 401 | Not authenticated: missing or wrong credentials, a credential of another space, or an expired token (code 401, ERROR_UNAUTHORIZED). |
| 404 | No such record or entity (code 143 ERROR_NO_ENTITY, or 2006 ERROR_UNKNOWN_TYPE). |
| 422 | Validation failed (code 40000, with the failing fields) or a required parameter is missing (code 119). By default one failed item fails a whole batch and nothing is written. |
| 429 | Too many requests (code 182). Wait for the seconds in Retry-After, then retry. |
| 500 | Unexpected server error (code 1000, ERROR_UNKNOWN). |
