core.config Module

Manage client connection and behavior settings.

DataverseConfig Class

Container for language, timeouts, retries. Immutable.

from PowerPlatform.Dataverse.core.config import DataverseConfig

cfg = DataverseConfig(
    language_code=1033,        # Default English (US)
    http_retries=None,         # Reserved for future
    http_backoff=None,         # Reserved for future
    http_timeout=None          # Reserved for future
)

# Or use default static builder
cfg_default = DataverseConfig.from_env()

Key attributes:

• language_code: int = 1033 — LCID for localized labels and messages.
• http_retries: int | None — (Reserved) Maximum retry attempts for transient errors.
• http_backoff: float | None — (Reserved) Backoff multiplier between retries.
• http_timeout: float | None — (Reserved) Request timeout in seconds.

core.errors Module

Structured exception hierarchy for SDK operations.

DataverseError (Base)

Base exception for SDK errors.

from PowerPlatform.Dataverse.core.errors import DataverseError

try:
    # SDK call
    pass
except DataverseError as e:
    print(f"Code: {e.code}")                # Error category
    print(f"Subcode: {e.subcode}")          # Specific error
    print(f"Message: {e.message}")          # Human-readable
    print(f"Status: {e.status_code}")       # HTTP status (if applicable)
    print(f"Transient: {e.is_transient}")   # Retry-worthy?
    details = e.to_dict()                  # Convert to dict

ValidationError

Validation failures during data operations.

from PowerPlatform.Dataverse.core.errors import ValidationError

MetadataError

Table/column creation, deletion, or inspection failures.

from PowerPlatform.Dataverse.core.errors import MetadataError

try:
    client.create_table("MyTable", {...})
except MetadataError as e:
    print(f"Metadata issue: {e.message}")

HttpError

Web API HTTP request failures (4xx, 5xx, etc.).

from PowerPlatform.Dataverse.core.errors import HttpError

try:
    client.get("account", record_id)
except HttpError as e:
    print(f"HTTP {e.status_code}: {e.message}")
    print(f"Service error code: {e.service_error_code}")
    print(f"Correlation ID: {e.correlation_id}")
    print(f"Request ID: {e.request_id}")
    print(f"Retry-After: {e.retry_after} seconds")
    print(f"Transient (retry?): {e.is_transient}")  # 429, 503, 504

SQLParseError

SQL query syntax errors when using query_sql().

from PowerPlatform.Dataverse.core.errors import SQLParseError

try:
    client.query_sql("INVALID SQL HERE")
except SQLParseError as e:
    print(f"SQL parse error: {e.message}")

data Package

Low-level OData protocol, metadata, SQL, and file operations (internal delegation).

The data package is primarily internal; the high-level DataverseClient in the client module wraps and exposes:

• CRUD operations via OData
• Metadata management (create/update/delete tables and columns)
• SQL query execution
• File upload handling

Users interact with these via DataverseClient methods (e.g., create(), get(), update(), delete(), create_table(), query_sql(), upload_file()).

extensions Package (Placeholder)

Reserved for future extension points (e.g., custom adapters, middleware).

Currently empty; use core and client modules for current functionality.

models Package (Placeholder)

Reserved for future data model definitions and type definitions.

Currently empty. Data structures return as dict (OData) and are JSON-serializable.

utils Package (Placeholder)

Reserved for utility adapters and helpers.

Currently empty. Helper functions may be added in future releases.

client Module

Main user-facing API.

DataverseClient Class

High-level client for all Dataverse operations.

from azure.identity import InteractiveBrowserCredential
from PowerPlatform.Dataverse.client import DataverseClient
from PowerPlatform.Dataverse.core.config import DataverseConfig

# Create credential
credential = InteractiveBrowserCredential()

# Optionally configure
cfg = DataverseConfig(language_code=1033)

# Create client
client = DataverseClient(
    base_url="https://org.crm.dynamics.com",
    credential=credential,
    config=cfg  # optional
)

CRUD Methods

• create(table_schema_name, records) → list[str] — Create records, return GUIDs.
• get(table_schema_name, record_id=None, select, filter, orderby, top, expand, page_size) → Record(s).
• update(table_schema_name, ids, changes) → None — Update records.
• delete(table_schema_name, ids, use_bulk_delete=True) → str | None — Delete records.

Metadata Methods

• create_table(table_schema_name, columns, solution_unique_name, primary_column_schema_name) → Metadata dict.
• create_columns(table_schema_name, columns) → list[str].
• delete_columns(table_schema_name, columns) → list[str].
• delete_table(table_schema_name) → None.
• get_table_info(table_schema_name) → Metadata dict or None.
• list_tables() → list[str].

SQL & Utilities

• query_sql(sql) → list[dict] — Execute read-only SQL.
• upload_file(table_schema_name, record_id, file_name_attribute, path, mode, mime_type, if_none_match) → None — Upload to file column.
• flush_cache(kind) → int — Clear SDK caches (e.g., "picklist").
