If you want to add the base set of OG-tags to your pages, you can do this entirely in Twig. Create a small file in your partials folder, like _og_tags.twig.

{% if record|default() %}
    {% set title %}{%- if record|default -%}
        {{- record|title ~ ' | ' -}}
    {%- endif -%}
        {{- config.get('general/sitename') -}}
        {%- if record|default == null and config.has('general/payoff') -%}
                {{- ' | ' ~ config.get('general/payoff') -}}
        {%- endif -%}{% endset %}

    {% set image %}{{ url('homepage') }}{{ record|image|replace({'/files': 'files'}) }}{% endset %}
    <!-- Primary Meta Tags -->
    <meta name="title" content="{{ title }}">
    <meta name="description" content="{{ record|excerpt(160) }}">

    <!-- Open Graph / Facebook -->
    <meta property="og:type" content="website">
    <meta property="og:url" content="{{ canonical() }}">
    <meta property="og:title" content="{{ title }}">
    <meta property="og:description" content="{{ record|excerpt(160) }}">
    <meta property="og:image" content="{{ image }}">

    <!-- Twitter -->
    <meta property="twitter:card" content="summary_large_image">
    <meta property="twitter:url" content="{{ canonical() }}">
    <meta property="twitter:title" content="{{ title }}">
    <meta property="twitter:description" content="{{ record|excerpt(160) }}">
    <meta property="twitter:image" content="{{image }}">
{% endif %}

Then, where applicable, add the include to your template. Often this is placed right below the <title>-tag:

    {% include 'partials/_og_tags.twig' %}
